Intermittent "The Server is Not Reachable" for some users on mobile

Troubleshooting

Hi Dustin,

Welcome to the Mattermost community forums, and we’re sorry to her about the frequent connection issues.

Let’s try to troubleshoot this problem together. Here are a few suggestions:

  1. Check network connectivity: Ensure that the affected staff members have a stable internet connection on their mobile devices. You can ask them to try accessing other websites or applications to see if they encounter any network-related issues.
  2. Update the Mattermost server: Make sure your Mattermost server is up to date. Check if there are any available updates for the server, and if so, consider upgrading to the latest version. This could potentially resolve any known issues related to mobile connectivity.
  3. Verify mobile app configuration: Double-check the configuration settings on the mobile app for the affected staff members. Ensure that the server URL is correct, and that there are no typos or missing characters. Also, confirm that the app is set to use the appropriate port and protocol (HTTP or HTTPS) for your setup.
  4. Restart the Mattermost server: Try restarting the Mattermost server running on your Synology NAS. Sometimes, a simple server restart can resolve temporary connectivity issues.
  5. Check firewall or network restrictions: Verify that there are no firewall rules or network restrictions blocking the mobile app’s access to the Mattermost server. Check if any network settings or firewall configurations have changed recently.
  6. Review server logs: Check the Mattermost server logs to see if there are any error messages or warnings related to the mobile connectivity issues. The logs might provide more insight into the root cause of the problem.

If none of these suggestions resolve the issue, please provide more details about your setup, such as the reverse proxy configuration, any recent changes to your environment, or any other relevant information. This will help us in further diagnosing the problem and finding a solution.
