Using legacy mode seems to have solved the issue for me as well.

Establishing the connection is a lot faster now as well.

I'll try changing the NLA and TLS settings and let you know.

However, note that I did not change NLA or TLS settings between those two tries, just the host/IP of the.server.

This issue is also not as consistent as the 131085 error I had before, as now I am able to connect sometimes just by retrying.

Yes, the log contains both attempts

I've attached the log file.

These are two connection attempts to the same machine.

The first one terminated without any message.

The second I tried connecting to the IP address of the machine directly instead of its DNS name, and it returned the popup message "unable to connect"

I was also getting 131085 messages when connecting to some (not all) servers.

Always the same servers that did not work.

When trying this version, I can connect to some servers that previously didn't work.

But now on most others, I cannot connect and I do not get any error message (just "not connected").

Open external always works fine.

Edit: I now also sometimes get the popup: Unable to connect to host
