Hello everyone,
We are having the "can't connect, RD Gateway server temporarily unavailable" on RDWeb, only when accessed externally. Internally, the same external URL works. Server 2016.
This feature was working externally some time ago and we are not sure of what exactly broke it.
BPA's only warning is:
"The RD Gateway server SSL certificate must be configured with a valid certificate subject name
Severity: Warning
Problem:
The Remote Desktop Gateway (RD Gateway) server Secure Sockets Layer (SSL) certificate may not have a valid certificate subject name.
Impact:
If the RD Gateway server is configured to use an SSL certificate with a certificate subject name that is not valid, users cannot connect to internal network resources (computers) through the RD Gateway server.
Resolution
Use the RD Gateway Manager tool to select a valid SSL certificate for the RD Gateway server to use."
We have tried other certificates and the result is the same. All other certificates are also ok, they are valid and were made from Let's Encrypt.
Any help will be highly appreciated!
