ECP error.pngWe have MS Exchange 2019 CU12 . All was fine but since two days back we are not able to open ECP or Admin center and getting the error:

Server Error in '/ecp' Application.

Runtime Error__Description:__ An exception occurred while processing your request. Additionally, another exception occurred while executing the custom error page for the first exception. The request has been terminated.

There is no DAG and its a standalone server. No updates or installations done on it in the past two days. Issue started two days ago on Friday . Its running on Windows 2022 DC edition.I have checked eventlogs and could not find anything. We have already migrated to cloud (mailboxes), there are some connectors on this server for on-premise Applications but nothing much is done apart from some troubleshooting and migrating few DL's to cloud. Can anyone assist. (There is an HTTPS error but its there for a while, not related to this)
