Can anyone explain what is the problem??

I have the same problem. Looks like the openSSL is not visible.

bugaenko-cyber Did you fixe this issue?

[bugaenko-cyber]

I did not find a solution, while everything works on the old server. This problem is new. As soon as I decide I will let you know.

[aliks-os]

I already found solution. The libs libcrypto-1_1.dll and libssl-1_1 were added to the binary folder and all works like a charm :)
