Re: Creation of WebSocket tunnel to guacd failed - Guacamole 1.5.4
Hi Viji Sankar, From the log message, we can see that the Apache Guacamole Client couldn't connect to the guacd (the Apache Guacamole Server). Is the guacd running on the same pod as the guacamole client is running? If so, you need to check if the guacd is running. If not, you need to check if the port (default 4823) of the guacd is exposed.

Re: Log in to Gnome Shell RDP
Hi Horváth Csaba, Did you try to connect to your Gnome's built-in RDP server with the MS Remote Desktop Connection application (mstsc.exe)? I'd like to know if you're able to connect to it with mstsc.exe.

Re: Aw: Re: 1.5.4 - The connection has been closed because the server is taking too long to respond.
Hi Michael,
When the guacd fails the connection to a sftp server, the guacd stops the
connection to the RDP server.
The "SSH handshake failed." error message shows that the guacd failed the the
connection to a sftp server configured by you.
As you can see the following code, you can know what I mean:
https://github.com/apache/guacamole-server/blob/master/src/common-ssh/ssh.c#L522-L528
https://github.com/apache/guacamole-server/blob/master/src/protocols/rdp/rdp.c#L775-L785
Best regards,
Jimmy

Re: Aw: 1.5.4 - The connection has been closed because the server is taking too long to respond.
Hello michael böhm,
From the guacd's log, it seems that your sftp configuration has a problem.
```
guacd | guacd[47140]: INFO: No security mode specified. Defaulting to security
mode negotiation with server.
guacd | guacd[47140]: INFO: Resize method: display-update
guacd | guacd[47140]: INFO: No clipboard line-ending normalization specified.
Defaulting to preserving the format of all line endings.
guacd | guacd[47140]: INFO: User "@0fbf93c3-a8f2-4612-9212-56ec2772e71b" joined
connection "$8ceea3c6-da39-4690-9b21-73e5375122ec" (1 users now present)
guacd | guacd[47140]: ERROR: SSH handshake failed.
guacd | guacd[1]: INFO: Connection "$8ceea3c6-da39-4690-9b21-73e5375122ec"
removed.
```
The above highlighted log message shows that the guacd is unable to connect the
sftp server configured by you.
If the sftp connection fails, you can't connect to the RDP server.
So, please check the sftp configuration and the sftp server.
Best regards,
Jimmy
