Brand new Photon 2 keeps disconnecting and reconnecting to cloud

Cloud
1

Hi guys,

I have 10 new photons; all of them except one seem to be working fine. One of them, no matter what I do keeps disconnecting from the cloud then reconnecting every 1 to 3 minutes. I've flashed, restarted, ran setup again, ran device doctor, etc.. all multiple times and with nothing on it (or a simple LED blink app) it still loops.

0000269541 [comm.protocol] ERROR: Event loop error 1

Any thoughts? None of the other 9 (which are right next to this device and have the same particle antenna, and are connected to the same wifi network) are having any issues.

Here's a log file, taken immediately after I ran setup again:

I don't know specifically what's wrong, but whatever it is, it consistently takes 80 seconds to occur:

0000105304 [system] INFO: Cloud connected
0000185643 [comm.protocol] ERROR: Event loop error 1

0000189191 [system] INFO: Cloud connected
0000269541 [comm.protocol] ERROR: Event loop error 1

0000272721 [system] INFO: Cloud connected
0000353345 [comm.protocol] ERROR: Event loop error 1

I'd try increasing the logging level to LOG_LEVEL_TRACE so the keep-alive pings are logged. I'd guess that the first one works, and the second one has three retries then the connection is reset.

Hey Rick,

Thanks for the suggestion; there was a lot more info in that log level. To troubleshoot I connected the Photon2 to my cellphone wifi access point, and it wasn't dropping off at all. I connected it back to my home wireless network (where it continued to connect and disconnect) and I checked the router system logs. It was showing this:

2023/08/10 09:43:38 Kernel event ICMPv6 RA: ndisc_router_discovery() failed to add default route.

I googled that and it looks like it's a known issue with the router / modem I have. I rebooted and haven't seen the error with that Photon2 since (for a few hours now anyways).

Thanks again for the reply! Hopefully it's all working now.
