@girish many thanks for the advice I did as you asked and I could not telnet to the server via the terminal app, so I then went to the cloudron server and tried it from there it would also not work, which lead me down a bit of rabbit hole Eventually I managed to find and issue with the virtual nic on the server itself and managed to resolve that, and now it is working perfectly. Not sure how I missed it but you helped me find so many thanks. Kind Regards Scott

@dark_dragone not 100% sure but I think search domains is a client feature. This means that docker (the DNS client on behalf of the guac container) should be configured to have a dns search. See https://docs.docker.com/config/containers/container-networking/ (--dns-search). Maybe you can quickly try by editing /etc/systemd/system/docker.service.d/cloudron.conf and restarting docker. I think you can also add it in your local machine's /etc/resolv.conf

@robi The universe gave me a hint this could be due to a session timeout, will re-test.

@tshafaat211 is there anything in the guacamole logs - https://docs.cloudron.io/apps/#log-viewer ?

@rez I see. Cloudron apps do not run in host mode because we need the network isolation for security purposes. Still I am not sure I understand why a docker container cannot access external network regardless. I thought this was taken care of by linux routing.

@jonlabs If you open a web terminal, are you able to telnet ip-of-server 22 (22 is the SSH port). Does it connect?

@girish Thank you for your prompt action on this. I have tested and all is now working as intended.

@girish Thanks! - should have figured that out - didn't see the button

Fair enough, currently it has no memory limit set, so it uses the default 256MB. Which is probably quite low for java apps.

I had to look up why this was needed. https://github.com/glyptodon/clipboard-permission-manager has an explanation.

@murgero Thanks for following up, apologies for not seeing this sooner. I don’t really know if they are fully compatible. I started using it a number of years ago since it then was a more secure and faster VNC implementation. It works cross platform by downloading a server application from RealVNC, and then registering an account with them. The free tier allows for 5 desktops/servers. The added benefit from a simplicity point of is that you connect via the client app through their servers, eliminating the need to open standard VNC ports in your firewall. I never did manage to find out how, and if, it is possible to connect in other ways. That’s why I was hoping someone else knew... Thank you very much!

@odie Good catch! This was an oversight on my part. I have pushed an update to fix this.
