Galaxy Note 8 "Authentication Error Occurred"

Anybody having issues connecting to Wifi with Galaxy Note 8? I originally had no problem but within the last month it has started giving me an Authentication Error Occurred. I kept resetting my home router and I was finally able to get it to connect to that one. However, at work I use a mobile hot spot and up until a month ago was able to connect seamlessly. Now, I have tried everything that I can think of and it wont connect. I did a soft reset, restarted in safe mode, reset network settings, re-typed the password. I have looked at countless websites and videos to no avail. Any ideas?

It is important that you are able to get a stable, reliable connection to your Wi-Fi, <<removed>>. Authentication errors can be a major headache. One approach that might help is to go into your Settings menu, go to the Wi-Fi section, tap Advanced, Scroll down to "Keep Wi-Fi on during sleep," select "Never" and power cycle the device, then go back into the Settings menu, go to the Wi-Fi section, select advanced again, and set "Keep on during Sleep" back to "Always."
