Hello,
I have installed xRDP on a 22.04.4 LTS Dekstop system and changed the configuration as follows:
port=tcp://:1234
(to enable IPv4, as previously only IPv6 was listened to)
See here: https://stackoverflow.com/questions/67566142/does-xrdp-0-9-5-only-support-ipv6-and-not-ipv4
The service starts cleanly and without error messages. As soon as I start the connection from a Windows10 system via RDP, I also get the corresponding xRDP window with the input mask. However, when I enter and confirm the login, the RDP session closes again immediately.
I have already released port 1234 in the Windows firewall - unfortunately without success.
I can see some error messages in the log, but I am not sure how relevant they are due to various statements in different forums:
