Hi, After starting the Dashboard on another pc on the domestic network, when I try to load the Cockpit it opens the login page then nothing, just a white, or black browser page. I ran the journalctl and got the following:

asl@node520441:~ $ journalctl -u cockpit

Mar 11 12:29:43 node520441 systemd[1]: cockpit.service: Deactivated successfully.

Can anybody suggest a possible cause, and / or solution.

Any help appreciated.

This is an open issue with cockpit for some time now. Please see
https://github.com/cockpit-project/cockpit/issues/14896

This can also be caused by a problem with a server certificate or firewall configuration.

Thanks for update, I checked firewall and looks ok, I am using Opera as browser necessary ports also forwarded.

Well I seem to have got the Dashboard to work. On my local screen attached to the Rpi, I ran nmcli device wifi list and this gave me a list of about 7 networks in my area, including mine. This told me that my node whilst having a preconfigured SSID an PASSWORD was not actually connected directly. So i ran nmcli device wifi c [SSID] this came back with:-

Device “wlan0” successfully activated with [UUID from “wifi manager” setting in Terminal].

Now the dashboard works fine every time.

Hope this helps
