I am running RD 1.5.1 on Ubuntu 22.04. When I try to display the Dashboard, it shows a blank screen. I had uninstalled it previously and reinstalled it. I followed the instructions in the Troubleshooting section and reset to factory defaults but still no dashboard. My only non-default setting is I have disabled Traefik. I searched through this channel and see that some others have had this problem when they uninstalled RD. They had to manually remove some files. These were all on Windows and I did not see a list of files that should be cleaned out. If I start RD from the command line, I see the following error messages when I then try to display the dashboard:

(node:11886) electron: Failed to load URL: <http://127.0.0.1:9080/dashboard/c/local/explorer> with error: ERR_CONNECTION_REFUSED

I have a separate Ubuntu 22.04 system where the Dashboard is displayed with no problem. Any thoughts?

It is most likely a port conflict. Are you using the Logitech Ghub software? If yes, then https://github.com/rancher-sandbox/rancher-desktop/issues/1890#issuecomment-1222775512 shows a workaround

Thanks for the quick reply. I'm not using Ghub and I have not been able to identify any other process using port 9080. I don't see any hints in

iptables

or the Ubuntu firewall either (not that I know what I'm talking about here).
