I use Cloudflare to do developing directly over HTTPS urls. Today suddnely I started getting error as " Web server is down Error code 521 "

Even when the port is running on the server.
What to do in this case?

I uninstalled, re-installed the server but no luck yet.

Are there any logs from the cloudflared service?

And what about when you try to visit the site? Does it show in cloudflared logs as well?

#

Now I have started receiving "Connection timed out"

In the cloudflared logs?

tough warren Dec 1, 2023, 10:23 PM

#

No, there are no additional cloudflared logs

#

I don't want to create recreate tunnel as there a lot of domains connected.

#

Odd question but can you verify that the CNAME record is pointing at the correct tunnel id?

tough warren Dec 1, 2023, 10:25 PM

#

Also, I have checked about incoming and outgoing connect. Everything is working in that context.

#

Already did, yes the CNAME record is correct.

#

Somehow it automatically worked.
