VM Logs In To Left Menu & Blank Right Hand Screen

Virtualmin

SYSTEM INFORMATION
OS type and version Ubuntu 22.04

Virtualmin version Latest?
Webserver version Apache

Last week all was good and I do not think I have run an update since earlier in the week.

When I now log in, I get the (occasional) ‘Your connection is not private’ browser message, which I then pass and go to the VM dashboard page. The Left column shows but the main screen does not.

When I select Dashboard or Terminal, I get the red ‘Connection Lost’ message!.

I have rebooted the server, without luck.

So, it is accessing the system but an error occurs when I try to do anything.

I am trying to log in at server host level to see if that gives anything away, but any thoughts would be appreciated.

Hello,

Thanks for reaching out!

What is the domain name you are having a problem with? Also, is the SSL Certificate for the domain valid? Can you provide a screenshot of the “Manage Virtual Server ⇾ Setup SSL Certificate” page?

Hiya,

I managed to update the server from the hosts console (I hope that isn’t an issue) which found some PHP files and, slowly, the access & dashboard visibility came back.

However, I still cannot access many of the features on each server, including SSL '(red ‘Connection Lost’ message), so cannot access that part!

What’s the TLD you’re having trouble with? Is it on the HSTS preload list?

Does this issue also happen in an incognito tab or in another browser? If so, what SSL certificate is returned by the server?

Sorry, not sure what that is!

Anyway, all seemed to work via incognito! I didn’t even think it could be the browser!

Thanks for that pointer.
