SMBClient does not accept domain.example.com@SSL URL format, until it sometimes does for a while – WebDAV redirect not triggering

So I have set up an SMB server running over HTTPS, and am trying to connect to it via a URL like \domain.example.com@SSLpathtofile.txt

However, Windows fails to connect to it, and the SMBClient logs reveal an object not found error relating to domain.example.com@SSL – clearly it does not like that syntax

So I tried removing it – \domain.example.compathtofile.txt, thinking that when SMB fails, the WebDAV redirector should take over – but it does not, the SMBClient log shows a timeout error, then nothing.

The odd thing is, in some cases, when I explicitly open anything on the server first, with net use for example on the @SSL path, everything else using starts working right away as expected until a reboot

I’m assuming something is being cached to bypass the DNS issue

My question is, what am I doing wrong, and how do I get the WebDAV redirector to properly trigger for 1st time connection attempts
