Cant get phone to registered after Rest log off

I just got some now yealink t48g phones. I got them registered with EPM, but was having issues with phone apps, they would say that specific module was not allowed with that extension. (which was odd because I explicitly allowed those phone apps in UCP. The only one that would come up was the logon app. So like an idiot I hit logoff. The phone had a please wait banner for like 10 minutes, then i finally hit cancel. Now I cant get the phone to register!! I’ve tried assigning it to a different extension, I deleted it from EPM all together, then try adding it back. Factory resetting the phone, etc. Nothing I do seems to get the phone to register. Did I screw something up?

Nevermind, turned out to be a fail2ban issue. A subnet i forgot to whitelist
