WiFi disconnect before getting IP address

[0xffff]

I have 2 systems running the same code - one works well, the other doesn't. In the working system, WiFi connectivity is no problem - In my logs I see:

Code: Select all

[2020-04-02T00:07:27.619] W (25245585) WIFI: Wifi is Connected

In the second system, where it cannot connect easily, I see:

Code: Select all

Where the messages with tag wifi come from the IDF and those with WIFI are my log messages and the result of the callback for WiFi events from the arduino library.

I'm trying to figure out what's going on - why could the wifi system go from state run back to auth, and what does the ec0 mean? Note that the access points, although with same name, are in geographically different locations (not the same network).

What does wifi: n:1 0, o:1 0, ap:255 255, sta:1 0, prof:1 mean? It seems like a reset type of message.
