Behavior

Intermittent failure to connect to wifi AP. Behavior began after connecting to a second network and then trying to connect to the first network again. Confirmed “secrets.py” is correct as Wifi sometimes connects. Connection attempt seems to take 2-3 times longer than standard when the error occurs and then the error below appears in the REPL.

Traceback (most recent call last):
  File "code.py", line 30, in <module>
ConnectionError: Unknown Failure 205

Additional Info

Not sure whether resetting my router fixed the issue temporarily or it cleared up on its own briefly. Error occurs when using the simpletest above and when using magtag.network.get_local_time()
