Hello all!
Out of nowhere upon opening B1 Client we get the message "There is a problem with the server's security certificate.
The Security certificate is not from a trysted certifying authority. SAP Business one is unable to connect to the server."
Logging from the server is successful without any problems, this only appears when trying to log in from a client, before even asking for credentials.
The users were working and it was noticed as one of them restarted their computer.
The ones who were still logged in were able to continue working.
The server was restarted in case it would have been helpful and all users now have the same problem. Still logging in B1 through remote desktop is possible.
