osTicket 1.18.1 was working for alst 2 years with Fetch email with oAutho2 plugin
Upgraded to 1.18.4 and PHP 8.4
Had the IdP Config token expired
Updated OAuth2 to Version 0.6
Removed the token, recreated another Client Secret on the same App Registration on Microsoft Entra and did oAuth2 Authorisation. On clicking Submit on the IdP Config page, I get the Micorosoft Credentials page. On entering the credentials of the helpdesk email adress, jumps onto the Support Center Home page. Screeshots attached.
please advise
