Would it be possible to output more information in the Journal log when the connection to the server "is lost" ? At least they could be sure this is a TLS issue.

Can you check which TLS version is running ? Just to confirm this is the issue. I used my browser to check it :

Just an idea.

 

my windows server 2016

Ok so it seems the issue is not related to TLS.

Did you try with MT5 build 3661 ?

I don't think using the browser is a good idea to verify which TLS version is used by the operating system. Many browsers use their own TLS/SSL implementations irrespective of what the OS has implemented.

Here is a better way to verify it ...

The following information may also be helpful ... Windows and Supported TLS Versions
