Issue with connecting to WiFi on Pixel Tablet

Hi all, I'm having an issue with connecting a Pixel tablet to WiFi.

All other devices connect just fine but this one device will not connect no matter what I do.

I have checked all firewall rules, I have disabled all ips, SSL decryption and it still will not connect.

The firewall is sophos home on a mini pc and the WiFi is ubiquiti u7 in wall and the firewall is in bridge mode connected to a unifi 8 port switch.

Thanks in advance for any help.
