Hello, I have a situation where most of the devices on my server stopped sending their location yesterday. I checked the position table of some of the devices that weren't updating their position, and it's not coming through. I checked several things, but to sum it up, I sent a check123456 to one of the devices that wasn't sending its position to check its status, and it said GPRS OFF. I removed the SIM card, and it has DATA and everything seems normal. I pointed this device to a Traccar test server, and it connected immediately and said GPRS ON. Any ideas on what I could check? Almost all the devices stopped communicating their location yesterday, and I've checked the MODEM and server, but I can't find the problem.
You should share your server logs.
I see a bunch of these you should probably resolve first:
2026-08-05 00:04:29 WARN: [T6faef979] error - An established connection was aborted by the software in your host machine - IOException (...)
2026-08-05 00:04:29 WARN: [Tf4a06ada] error - An established connection was aborted by the software in your host machine - IOException (...)
But also you need to provide more context. Which device in logs, what exactly is happening for that device etc.
