Error connecting to Apple ID server

Basically I was trying to clear my iPad and I think I may of clicked the wrong one because when I try to clear all settings and content it just says error connecting to Apple ID server, along with none of the options on the Apple ID working (not letting me sign out ect) the only option I can click is password and security. However when I click it it just says get a code on my other device. I’m logged into my iCloud on this phone yet I don’t receive any code? Please can someone tell me what’s wrong and how I can fix it I really need it for college
