So this is an interesting error, there is no reason why this starts failing after working without any issues but the main culprit is the firewall (check your virus software firewall setting) that does not allow you to connect to the wifi:
to fix:
to fix:
- turn off firewall on windows or virus software
- turn on wifi on PDANet mobile app
- connect from Windows machine
- should connect without any issues
- turn on firewall which should now include your wifi connection information in the networks settings if not, you will need to add.
So if you encounter this error again then you know that the firewall setting is the cause.
