Guacamole server error "The remote desktop server is currently unreachable" even RDP is working from default remote desktop connect

asquare
Hello,

I am getting the error message "The remote desktop server is currently unreachable" in case of some RDP access while it is accessible by a normal RDP client. The RDP has windows 2016 os and working fine. This is an issue some time for some RDP only not for all. The other RDP which are accessible also has the same os. Please help me to solve this issue. The log is below. I am not techy so please help me to solve this issue.

The logs below are Tomcat logs - can you also pull your logs for guacd and see what they are showing?

I'm not sure where your guacamole server is in relation to the RDP server, but the above messages indicate that there are some connectivity issues between Guacamole Client and the MySQL database - traffic is either getting blocked, or delayed in a huge way (the times above are like 10-15 hours).  So, it looks like there are probably some network issues with your Guacamole server - we're going to need a lot more detailed information (architecture, logs, etc.) to figure out what.

guacd logs should be in syslog somewhere - on Ubuntu 20.04.1 that is probably done via "journalctl", but also could be /var/log/messages or /var/log/syslog.
 

Environment:
Ubuntu 20.04.1 LTS (GNU/Linux 5.4.0-52-generic x86_64)
10 CPU cores, 60 GB RAM (guaranteed), 1600 GB disk space (100% SSD), 100% SSD disk space, UNLIMITED traffic, 1 Gbit/s port


That certainly looks robust enough.  Is your MySQL or MariaDB database running on that same server, or somewhere else?

Part of the point of using the mailing lists is that they are archived and reach out across the community. The entire community has the chance to assist and whatever is discussed here will be visible to others who need help in the future. The goal is to benefit the community as a whole.

Direct communication via chat would defeat all that.

Re: Guacamole server error "The remote desktop server is currently unreachable" even RDP is working from default remote desktop connect

mjumper

A few things to keep in mind when troubleshooting an issue like this:
  • When a connection fails, the full details of the failure will never be exposed to the user via the web interface. The error displayed there is intentionally high-level. It lets the user know something is wrong, but will not be very useful for troubleshooting. You will need to consult the guacd logs.
  • If you are able to successfully connect to some RDP servers but not others, there must be some difference between the servers that accounts for that. If you can investigate the differences between the RDP servers in question, that might tell you everything you need to know. If you are certain that the servers are reachable over the network, and there is no firewall on those servers blocking guacd from connecting, then the most likely cause would be authentication-related.
  • If the guacd logs are not revealing, enabling debug-level logging for guacd may help.
As Nick suggested, you should first locate your guacd logs, most likely within /var/log/syslog or journalctl. To enable debug-level logging for guacd, you would edit /etc/guacamole/guacd.conf and set the log level. The manual provides an example showing the format of this file, if it doesn't already exist:


With the possible exception of the log level, you don't need to specify anything that you aren't already specifying.

Re: Guacamole server error "The remote desktop server is currently unreachable" even RDP is working from default remote desktop connect

Hello,

I tried all what i can but there is not solution for this. I formatted the server where this Guaxamole is installed and reinstalled all again. I formatted the RDP server also but situation is still same. Now i m getting below message.

"The connection has been closed because the server is taking too long to respond. This is usually caused by network problems, such as a spotty wireless signal, or slow network speeds. Please check your network connection and try again or contact your system administrator."

I request you please help me to solve this issue as i m 100% non technical person. If there is a need to see any kind or log please tell me the path where i can saw that. If there is a need to increase trace lable and then see logs please tell me where and how can increase the trace lavel and then how i can see the logs etc. Kindly help me.

A few things to keep in mind when troubleshooting an issue like this:
  • When a connection fails, the full details of the failure will never be exposed to the user via the web interface. The error displayed there is intentionally high-level. It lets the user know something is wrong, but will not be very useful for troubleshooting. You will need to consult the guacd logs.
  • If you are able to successfully connect to some RDP servers but not others, there must be some difference between the servers that accounts for that. If you can investigate the differences between the RDP servers in question, that might tell you everything you need to know. If you are certain that the servers are reachable over the network, and there is no firewall on those servers blocking guacd from connecting, then the most likely cause would be authentication-related.
  • If the guacd logs are not revealing, enabling debug-level logging for guacd may help.
As Nick suggested, you should first locate your guacd logs, most likely within /var/log/syslog or journalctl. To enable debug-level logging for guacd, you would edit /etc/guacamole/guacd.conf and set the log level. The manual provides an example showing the format of this file, if it doesn't already exist:


With the possible exception of the log level, you don't need to specify anything that you aren't already specifying.

Hello Nick,

So nice of you to reply me so fast. I am not technical person just installed it and running. Now i m also not getting any other one to get it solved. Can you please tell me the path from where i can pull the logs which i can provide you the same and get it solved. The system has below config rest all please guide me please. It has Tomcat 9

guacd logs should be in syslog somewhere - on Ubuntu 20.04.1 that is probably done via "journalctl", but also could be /var/log/messages or /var/log/syslog.
 

Environment:
Ubuntu 20.04.1 LTS (GNU/Linux 5.4.0-52-generic x86_64)
10 CPU cores, 60 GB RAM (guaranteed), 1600 GB disk space (100% SSD), 100% SSD disk space, UNLIMITED traffic, 1 Gbit/s port


That certainly looks robust enough.  Is your MySQL or MariaDB database running on that same server, or somewhere else?

Re: Guacamole server error "The remote desktop server is currently unreachable" even RDP is working from default remote desktop connect

asquare
Hello,
I had a discussion over the email from my vps provider and get below response. If you can help me after seeing that?

As we can see, both your VPS are located in the same subnet for which reason a direct connection to each other is not possible without a static route.

You need to create a static route on each affected server.

To do so, please follow the steps as provided on the following website:

https://contabo.com/blog/creating-static-routes

If you have any questions or need help, please do not hesitate to contact us.

Please help me to solve that issue as all my work got stuck due to this.
