Unifi USG - guest portal issues

[MatthewL]

I am ready to put these pile of junk USG 3P's in the bin.

 

I have several of these at sites (not my choice) VPN back into network fine and that side works although internet speed is limited with some of the features of them.

 

I have multiple VLAN's on the USG, a voice one and 2 internet only VLAN's.

 

3 SSID's, corporate (radius), guest (radius) and guest (open to external portal server). The guest to portal server is the one I am having issues with can get it to let me put name and email in but then after that is random what will actually work, it should give 10 minutes of internet before it logs you off unless you authenticate on the email that you get. I have this same setup on none USG sites and its fine so its something USG related.

 

Any suggestions?
