cURL error 7: Failed to connect to localhost port 443: Connection refused

[USY]

Hi,

I am running XenForo Forum on my Plesk which running behind Cloudflare.
I get following erro log, which is showing me that the curl connection to localhost on port 443 is refused.


All curl's to localhost, 127.0.0.1 and 0.0.0.0 are refused:

root@srv:~# curl -vv localhost:443
*   Trying ::1:443...
* TCP_NODELAY set
* connect to ::1 port 443 failed: Connection refused
*   Trying 127.0.0.1:443...
* TCP_NODELAY set
* connect to 127.0.0.1 port 443 failed: Connection refused
* Failed to connect to localhost port 443: Connection refused
* Closing connection 0

root@srv:~# curl -vv 0.0.0.0:443
*   Trying 0.0.0.0:443...
* TCP_NODELAY set
* connect to 0.0.0.0 port 443 failed: Connection refused
* Failed to connect to 0.0.0.0 port 443: Connection refused
* Closing connection 0
curl: (7) Failed to connect to 0.0.0.0 port 443: Connection refused

UFW Firewall is disabled:

root@srv:~# sudo ufw status
Status: inactive

netstat show me that port 443 is active and listen


To be sure I also have turn OFF the "Security Level" on CF Firewall.



No matter what I've tried, so far unfortunately without success.

I would therefore be very grateful for any tip or solution to solve this issue.

Regards

Also loopback already exists.


So unfortunatelly this still doesn't solve the issue I got.

Please give your feedbacks.

I get also:


But the strange thing if I curl the doman. it works:

root@srv:~# curl -vv wns2-par02p.notify.windows.com

TCP_NODELAY set

There was a general outage which caused that.

XF 2.2 - Could not resolve host: wns2-ln2p.notify.windows.com

I'm getting quite a few of the following errors recently, can anyone shed any light on the cause? ErrorException: Push notification failure: cURL error 6: Could not resolve host: wns2-ln2p.notify.windows.com (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)...
