# Prompt or warning messages

Explains the causes, impact, and handling methods of common FIRST LINE prompts and warning messages, including permissions, login, data validation, operation conflicts, request frequency, and connection issues.

During the operation process, FIRST LINE will display prompts or warning messages depending on the situation to help you determine what problem is occurring and what to do next.

These messages do not necessarily indicate a system failure. Common situations include incomplete data entry, insufficient permissions, expired login status, the same service being handled by another specialist, or operations being performed too frequently in a short period of time.

{% hint style="info" %}
If the message shows a specific reason or field name, it is recommended to follow the prompt first. Only if the issue cannot be resolved through normal operation, or if multiple users are affected at the same time, should you contact the administrator, enterprise IT, or FIRST LINE.

## Common prompts and how to handle them

| Prompt type                                          | Messages you may see                                                                                | What it means                                                                                                                                     | What to do                                                                                                                                                                              |
| ---------------------------------------------------- | --------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Data does not meet the rules                         | Data does not meet the rules, required field prompt, field format error                             | The submitted data did not pass validation, for example a required field was left blank, the format is incorrect, or the data status has changed. | Correct the fields according to the prompt and resubmit; if the page has been open for a while, try refreshing it and then try again.                                                   |
| You do not have permission to perform this operation | No permission to perform this operation, unable to perform this operation                           | The current account does not have the corresponding permissions, or this operation is only allowed for certain roles.                             | Check the current permissions; if changes are needed, contact the internal company administrator.                                                                                       |
| Unable to view this content                          | Unable to view this content, content does not exist                                                 | The data may have been deleted, the URL may be invalid, or the current account may not have viewing permission.                                   | Return to the previous list and search again, and verify the account and permissions.                                                                                                   |
| Another specialist is already handling it            | A specialist is already handling it, the customer has been assigned to another specialist           | The same service has already been taken over by another specialist, and the system prevents duplicate handling to avoid conflicts.                | Reconfirm the responsible specialist and the latest service status; if it has already been taken over, no need to repeat the operation.                                                 |
| Requests are too frequent                            | Requests are too frequent                                                                           | Too many requests were made in a short period of time, so the system has temporarily restricted the operation.                                    | Wait a moment and try again, and avoid repeatedly clicking or refreshing. If it comes from an API/Webhook/automation, check whether duplicate calls are being made.                     |
| Authorized logins exceed the limit                   | Authorized logins exceed the limit, too many users are currently online                             | The number of users logged in simultaneously exceeds the number of licenses allowed by the current plan.                                          | Check whether any specialists who are no longer using the system are still logged in, and have the administrator confirm whether the number of licenses meets the requirements.         |
| Login expired / verification expired                 | Login expired, verification expired, re-login required                                              | The login status has expired due to inactivity for a long time, security reasons, or a change in verification status.                             | Re-log in according to the on-screen prompt; if it happens again immediately after logging in again, check the browser cookies, time settings, or the enterprise login environment.     |
| Incorrect account or password                        | Incorrect account or password entered, too many login attempts                                      | The login credentials are incorrect, or there have been multiple failed login attempts in a short time and you are temporarily restricted.        | Verify the account and password; if you forgot your password, use "Forgot Password." If you are temporarily restricted, follow the prompt and try again later.                          |
| Network connection offline / restored                | Network connection is offline, network connection has been restored                                 | The continuous connection between the browser and FIRST LINE real-time services has been interrupted or re-established.                           | First confirm whether the network is working properly; if it keeps happening, further check Wi-Fi, VPN, sleep mode, or browser background settings.                                     |
| Unable to complete the operation temporarily         | Unable to complete the operation temporarily, general error prompt                                  | The system or a dependent service is temporarily unable to complete this operation, or the data status has changed during the operation.          | Try again later; if it keeps failing, refresh the page and record the complete error message and the time it occurred.                                                                  |
| Network connection error / timeout                   | Network connection error, network connection timed out, operation temporarily unavailable           | The connection was interrupted during the request, the service took too long to respond, or a connection could not be established temporarily.    | Check your general network and VPN, refresh the page, and try again. If multiple colleagues experience it at the same time, check the enterprise network and FIRST LINE service status. |
| File upload failed                                   | Size exceeds the limit, file format not supported, upload timed out, network error, upload rejected | The uploaded file does not meet the restrictions, or the upload process was affected by network, permission, or service status.                   | Check the file size and format according to the prompt, confirm the network, and upload again; if necessary, try another file that meets the specifications.                            |
| Email sending failed                                 | The email was not sent, email address is incorrect                                                  | The mail service refused to send, account verification failed, settings are incorrect, or the recipient address format is invalid.                | Check the email channel settings and the error details; if there is an error code from the mail provider, ask the email administrator to help interpret it.                             |
| Delete or high-risk operation confirmation           | Delete data, are you sure you want to perform this operation?                                       | This is not an error, but a confirmation requested by the system before an irreversible operation or one that may affect existing data.           | Confirm the target of the operation and the scope of impact before deciding whether to continue.                                                                                        |

## Situations that require special attention

### Authorized logins exceed the limit

The simultaneous login quota is calculated based on the number of licenses the company has currently purchased. If a specialist does not log out properly, they may continue to occupy a login slot.

If this kind of prompt occurs frequently, it is recommended that the administrator confirm the current online users and actual licensing needs, rather than repeatedly logging in again.

### Network connection is offline

"Network connection is offline" mainly means the browser cannot maintain a connection to FIRST LINE real-time services,**It does not necessarily mean there is an issue with the FIRST LINE server**.

If it happens only occasionally and recovers quickly, you can continue using it and monitor it; if it occurs repeatedly within the same day, refer to the "Network offline reminder" for further troubleshooting.

### File upload failed

File upload prompts usually explain the reason directly, such as size exceeding the limit, unsupported format, upload timeout, or network error. Prioritize handling the prompt itself; there is no need to clear the browser cache first.

### Email sending failed

When using the email channel, some error messages come directly from the mail provider rather than FIRST LINE itself. If the error content includes SMTP, authentication, or mail server-related messages, it is recommended to also check the email channel settings.

## Still not sure how to handle it?

If you cannot determine the cause from the prompt, it is recommended to first record the following information:

1. **Full prompt text**: Do not just say "the system showed an error."
2. **Time of occurrence**: Include the date and approximate time.
3. **Steps taken**: Which page you were on and which button you clicked before it appeared.
4. **Scope of impact**: Only you, a specific account, or multiple users experienced it.
5. **Can it be reproduced**: Whether it still happens after refreshing or logging in again.

{% hint style="info" %}
If the prompt already clearly indicates a permissions, license count, file format, or data entry issue, it is recommended to handle the prompt content itself first; there is no need to clear the cache or reinstall the browser as soon as you see a warning.
