We unclaimed two xenons and one argon from a previously set up mesh network. When using the particle app to set up the argon again (in listening mode, then progresses to breathing white) we are only able to get past "connecting to the internet via Wi-Fi. Then, the set up fails during the “starting a secure session with the Particle device cloud” phase, and gives the error:
Your device failed to obtain an IP address. Please make sure your device has internet access.
This is strange because we have previously been able to set up mesh networks and boards on this same wifi (WPA2), and currently have a mesh running on a different account also using this same wifi.
