Unable to access internet from AP (multiple clients)

Hello,

I have a new issue that has come up for me with multiple clients that has prompted me to join up.
All these clients have UniFi WAP’s at their locations.
In the last 2-3 weeks they are all having the same issue where they cannot access the internet when connected to the Wi-Fi.
I have updated firmware and controllers and restarted units but all to no avail.
Internet access used to work so I am not sure what has changed and I am not finding anything that is out of the ordinary so I am hoping someone here has run into the same issue and can offer some insight into this issue.

Thank you,
Virgil
