Funny thing is, even tough I had NET::ERR_CERT_AUTHORITY_INVALID errors, I could accesss it with Chrome; now, after closing the window and trying again, I'm getting a HSTS message telling me that I can't override the invalid certificate and go through.
This is just the sort of monitoring utility I've been looking for! I've been looking for something that is easy to install and gives me basic monitoring. So glad you did this episode; Cockpit looks like a great possibility!
This seems pretty cool! Unfortunetly following your instructions I'm unable to access port 9090, it just times out. I tried allowing it on ufw but still no luck. Not sure what I could have missed, the offical docs make it seems like install and go.
