The problem is in the work of the authentication agent. There is Exchange 2019 in the DAG cluster. After installing the agent and working for some time, there are problems with user authorization with the error reason=2, while all users cannot log in through the web.At the same time, user authentication is successful on the server itself.

Dear AMRV,
first part of VerifyOTP for user ... log HTTP 200 is message that FortiAuthenticator confirm that OTP is good, and rest of error are strictly on Exchange/OWA agent.
Error "Server (ip address) rejected logon with reason: reason=2" point to some kind of limitation on exchange server itself. Please check if there is any limitation from which IP range you can access to OWA/ECP.
