Wifi keeps disconnecting, then reconnecting (Photon 2)

Connectivity
1

My WiFi keeps disconnecting (then trying to reconnect). I've tried two difference SSID's on our LAN (2.4Ghz and 5GHz) and I get the same result. I am on my home network. I normally use a wired connection so I haven't taken the time to connect wirelessly and see if it's a local network issue or not. But in case it isn't a local network issue and it's possibly related to either my device (and/or the code I working with) what are some things I can do to troubleshoot it? I have the serial monitor on so I copied and pasted the output below. I've went to device set up twice and "re-flashed" and reconnecting wirelessly but the issue still persists. At the moment, i'ts disconnected and re-connecting for at least 15+ minutes.

The output of "DNS server list changed" could possibly be a sign of my local network issue as the current SSID I am connected to use the ISP's DNS servers (which I normally stay away from). But the previous SSID did use a different DNS than ISP and still had issues so...

Any suggestions or advice on how to troubleshoot this further?

Hey -- I'd like our team to take a look, but we're working into the holiday break. I'd love someone from @Support to keep an eye on this thread for next week.

...looks like it was something with the library (or more like how I was (mis-)using it) that triggered this behavior.

After a period of several hours stable I decided to try to flash the same code again and same thing happened...so my code was the issue here.

Hope all have a great holiday! :tada:
