Windows RDP Problem

Hi Again!

I feel like I'm bombarding this list-serv with problems, sorry.

Running into an issue with RDP connection. So I have a few different VMs
running Windows 10. I can connect to some but not others, even though the
settings are the same on each. Here are the logs:

16:41:01.148 [http-nio-8080-exec-4] INFO  o.a.g.tunnel.TunnelRequestService

16:41:02.186 [http-nio-8080-exec-6] INFO  o.a.g.tunnel.TunnelRequestService
- User "user1" disconnected from connection "3". Duration: 1038 milliseconds

Connection 1 and 4 work without any issue. Anytime I connect to 3 I just
get disconnected with the same error. Not sure what else I need to be
looking at?

Ahh, will follow up the guacd logs. Thanks!

Since only one connection exhibits this problem, and consistently does so,
there *must* be some difference. If everything were the same, then
everything would work identically. I would recommend verifying the
configuration of the connection, the RDP server itself, and the network
between guacd and the RDP server.

You should look at the logs from guacd, which is the component of the
Guacamole stack which handles the actual RDP connection. The web
application doesn't connect to the RDP server, and thus can't be aware of
the nature of RDP connection failures; all the webapp is aware of is its
own connection to guacd and the HTTP or WebSocket connection from the user.
