Qlik Sense does not show webpage

[Anonymous]

Today, all of the sudden, the Qlik Sense server does not show the webpage.

We also have a dataload server, that shows the same problem.

All the services are running.

The server has been rebooted.

The services have been restarted one by one.

The QMC does not show up.

We had it listening on port 8081, but when I do a netstat, it doesn't show anything listening on that port.

Where do I start?

Ok, so now we've stopped the QVD server, and the central server is now responding.

But it of course shows a node is offline.

So now it's a problem with the QVD server I need to fix.

Check your logs on Qlik Server, could be an issue with Repository or DB.

Which logfile, on which server (on the central server or our qvd)? We trawled through the huge amount of logs and see a lot of different errors, but we can see they have been present for years.

What should we look for?
