SSL problem after Windows Creator Update

3 posts in this topic

Client only connects to server if "Use SSL encryption" unchecked; does not connect if checked. Seemed to work fine until I updated to Fall Creator Update. Server and client info and logs are below.

How do I connect with SSL encryption enabled?

Thanks.

Disable your firewall on the host machine and try connecting with SSL.  If that works, you will need to add an exception to your firewall configuration for it to work with the firewall on.

Thank you, but I still cannot connect with SSL even with firewall disabled. With firewall disabled, I am able to connect only if "Use SSL..."  is unchecked.
