    When i click to server and then back to Server Certificates the expiring certificate is still there, but the new one is gone.

    The cause is rather simple that your CA gave you the new certificate and expected you to merge it with the previous private key, but you cannot do that via IIS Manager (as the private key was probably deleted when you completed the request last time).

    Right now, you might use tools such as OpenSSL to export the private key from the installed old certificate, and then merge with this new certificate as a PFX file. Then simply importing that PFX file in IIS Manager can finish the task.
