Sharepoint HTTPS access stopped working suddenly

Hi,

we have a single server sharepoint 2013 server.

HTTP and HTTPS access are enabled for sharepoint site collection. The bindings and aam are set correctly.

The HTTPS access suddenly stopped working. Might be related to updates installation.

HTTP access is working properly.

When I create a new non sharepoint site in IIS the HTTPS access works.

When I create a new sharepoint site in IIS the HTTPS access does not work only HTTP access is possible. There is no response from the server.

Following event log error message might be related to this problem:

Schanel 36888 Error: A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 10. The Windows SChannel error state is 1203.

I checked the ULS, Event logs, changed bindings, tried creating new sharepoint web applications to find the source,

Any ideas?

Thanks,

Andrej
