Can you try this one and attach the debuglog (from the Data folder in the extracted zip)?

naps2-7.1.2-test3.zip

This build looks (some sort of) good, but seems something in my scanner went wrong: debuglog - Copy.txt

[dantmnf]

Nevermind it became operational after a few attempts.

[cyanfish]

Thanks, I think I need to add some retry capability for retrieving the scanned documents, that should hopefully make it more reliable.

[cyanfish]

7.2.0 should be more reliable when connecting.

And 7.2.1 should fully support HTTPS connections.
