Ok, so I'm back to stable synapse 39 and cryptlib 3.2.2.

So in summary, problem is in function:

TSSLCryptLib.Connect

In line:
if not SSLCheck(cryptSetAttribute(FCryptSession, CRYPT_SESSINFO_ACTIVE, 1)) then
      Exit;

Function cryptSetAttribute return value -22 and send it to SSLCheck.
This occur error:

FLastErrorDesc := GetString(FCryptSession, CRYPT_ATTRIBUTE_INT_ERRORMESSAGE);

Above string is "'敓癲牥爠灥牯整㩤䤠癮污摩瀠獡睳牯d'#0#0#0#0#0#0#0#0#0#0#0#0#0#0#0#0".
Instead of these
 chinese chars I see squares. GetString is calling:
cryptGetAttributeString(cryptHandle, attributeType, pointer(Result), l);
... where attributeType=13
I think something wrong is with function cryptSetAttribute (which
return -22) because it is suspending for 5-10 seconds.
