Photon 2 won't connect to cloud

Hardware

Works to local network, won't connect to my account. Was connected at one time. I have tried the on line doctor from both Windows and Linux. Log info:

repeats over and over.
Thanks for any help.

The error Internet available, cloud not reachable typically occurs when a firewall is blocking UDP access to the Particle cloud on port 5684. Your router typically sets up temporary port forwarding to allow the response from the cloud to come back to the device; the blocking could occur in either direction.

The cloud IP addresses may change as often as every minute. In your log, it used 18.214.12.187 which is a valid cloud IP address, so it does appear that DNS is working correctly. That can sometimes be an issue, but appears to be OK in your case.

The other possibility is a firewall that blocks access until terms of service are accepted. The Photon 2 cannot be used on a network with this type of access control.

Thank you. Case of severe stupidity between the headphones. Short version: connecting to the wrong router. One with very limited access, due to surveillance cameras.
Thanks a bunch for your help and patience with an old fool.
