Vehicle freezing issue

Hello,

I've been dealing with the same issue for a long time and haven't been able to find a solution. I thought it might be due to the server and the large number of devices, so I purchased a new server and directed 5-6 vehicles to it for testing, but I'm still encountering the same problem.

While the devices are operating regularly, they sometimes freeze and do not move. When I redirect them to the Traccar demo server for monitoring, there's no issue, but on my own server, the devices that are actively working get stuck after a certain day or period. When I remove them from the system and re-add them, they become active again and transfer the data on the device to the system.

Thinking it might be related to the configuration, I am using the initial setup configuration settings.

Configuration:

Looks like the server has not responded to the last message. Are you sure you're using the latest official release without any code changes?

Yes, I'm sure I did a new installation.

Maybe try setting up a timeout for connections.

How can I do this? And do you have any other suggestions? I don't experience this issue on Traccar demo servers; they work smoothly.

I had made all these settings for the previous servers, and I have now done the same for the new server. If the problem continues, I will write again for further support.

I face the same issue. were you able to fix? I followed the optimization guide as well
