I'm traveling to Iceland and brought my Particle Tracker One with me (EU/non-US band). It worked well on the first day but suddenly stopped connecting to the cloud and keeps blinking green for two days now.
I connected it to my computer and used the Particle CLI to check if I can debug it myself:
$ particle update

Okay! New keys in place, your device should restart.
$ particle identify
Your device id is e00fce68557cd01815149452
Your IMEI is 867648044132007
Your ICCID is 89883070000008809608
Your system firmware version is 6.1.1
I then used the Device Doctor to connect and generate the requested log file. Unfortunately, I'm not allowed to upload it here but it contains lines like these:
Is this working now? It appears that the device was able to connect and there are call detail records for successful data transmission on Nova on the 7th.
Hi @rickkas7, thanks for checking the status in the background. It did work indeed the day after. I left it on the desk and it somehow managed to get back online. On my journey, I must have found another coverage hole, as I'm back with a blinking green device. I assume once it loses connectivity, it's stuck in a loop and I'm trying to get it out of its misery. Do you have an idea what's missing given these logs?

I think I'll let it drain its battery over night and check again tomorrow.
I can't tell from that portion of the log. Prior to the beginning of the log it probably failed to connect because it reinitialized the cellular modem, which it does after 10 minutes of failing to connect. There are a bunch of messages for GNSS, which doesn't depend on cellular. After the end of the log there are probably some more cellular modem logs (mostly AT commands) that might have some information, but probably it's just unable to connect to a compatible tower.
Thanks, the logs pretty much keep repeating themselves. I found this one that could be of interest:
0008799480 [app.gps.ubx] INFO: AOPSTATUS: iTOW:410819000ms, aopCfg:1, aopStatus:0
0008802058 [net.pppncp] ERROR: PPP error event data=5
0008804296 [net.ppp.ipcp] ERROR: Peer NAK'd an option unknown to us
However, it doesn't say which of the option is unknown. Does that say anything to you?
Also, is there a command to restart the device via USB so that I don't have to wait until the battery is drained or use a screwdriver to get to the battery and quickly unplug it?
