I have a super urgent school job to finish, and I urgently need access to my school's VPN. However, I can't authenticate using my school network account (<Mod remove PII>@student.main.ntu.edu.sg) which is different from my main school account (<Mod remove PII>@e.ntu.edu.sg).
I tried re-adding my authenticator for my network account, but I just can't. And I have no access to it anymore. PLEASE HELP!

I've tried using another account which has I have access to the authenticator but the vpn portal still shows an "authentication error". Maybe it's a laptop setting error?
Are you using network account to access VPN portal? What VPN are you using? What Authenticator app are you using? It is Microsoft Authenticator or any third party Authenticator?
HI, I've figure out the issue. The vpn domain address was changed and it wasn't updated. The issue has been solved. Thank you for your help and response
looks like your login email address had been changed in different domain, so it may give error at the time of login.
