This will work differently on e-code and c-code. I am speculating if this is a protocol based solution for XProtect Enterprise, Professional, Express or similar that you now try to run in XProtect Corporate, Expert, Professional+, Express+?
I wrote in the title of the request, my version is “XProtect Express+ 2019 R2”, i try to connect with the “LoginDotNetSoap” and it work fine with “C” configuration.
Which log can I analyze to see if my requests arrive?
