There is a troubleshooting guide for it.
Check these:
Check that the IP configured on your phone (traccar client - server url) is correct. It should be same IP as your server. ifconfig
should show you your IP on your server. Then, your port should be 5055.
e.g: server-name:5055
Also, check that location is turned on your phone.
