Mike Jumper commented on GUACAMOLE-1862:
----------------------------------------
guacd is not hanging or waiting for the CLIPRDR channel in this case. That log
message indicates only the following:
* The RDP server has not responded to the request to connect of the CLIPRDR
channel.
* Received clipboard data from the client has been dropped and not sent to the
RDP server at all, since the CLIPRDR channel is still not connected.
Given the context, it sounds like:
* Your RDP server is hanging, hence the lack of response to the request to
connect CLIPRDR.
* With the RDP server hanging, lack of graphical updates gives the appearance
that guacd is hanging.
* After reloading, the RDP server coincidentally manages to get past whatever
was causing it to hang.
If your RDP server shows no inbound connection in the case of the apparent
hang, that suggests that something on the network is transiently preventing the
outbound RDP connection from guacd to your RDP server. There is definitely no
state maintained between connections that would cause one attempt to establish
a TCP socket and another attempt to _not_ establish a socket. Things would
follow the same code path in both connection attempts.

> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1862
> Project: Guacamole
> Issue Type: Bug
> Components: guacd
> Affects Versions: 1.5.3, 1.5.4
> Environment: OS: Ubuntu 22/04
> GUACD Docker: Ubuntu 22/04 -> same issue on original Docker Image (Alpine
> Linux)
> Reporter: HUBERION
> Priority: Minor
> Attachments: Hanging.txt, Successfuly_after_CTRL-R.txt
>
>
> After creating a adhoc Connection via a custom AuthenticationProvider
> Extenions sometimes (about 20%) of the cases the GUACD hangs and stays in
> this stage with the log "Clipboard data has been received, but cannot be sent
> to the RDP server because the CLIPRDR channel is not yet connected."
> Refreshing with CTRL-R in the browser solves the issue normally. We think
> that the GUACD is not evenen opening a Socket connection to the Remote hosts.
> The Issue exists on all 1.5.X Version, most likely also on older.
> Tested with newest Firefox/Chrome browser.
> Remote Server = Windows 2019.
> RDP Parameters: security=nla, ignore-cert=true, server-layout=de-de-qwertz,
