Currently upcp / updatenow are failing nightly on my CentOS6 / WHM 11.78.0.18 box...

Code:

And this ultimately results in...

(NB: log snippets are from two separate runs of upcp, hence date stamp oddities. Disregard.)

From the server, I can manually wget http://httpupdate.cpanel.net/cpanelsync/TIERS.json from CLI without an issue...

Code:

Any further suggestions anyone can think of to aid diagnosis? I'm guessing the issue only occurs via the specific perl httprequest class within updatenow... SSL checks show https unavailable for all the httpupdate mirrors (- Removed -) so am assuming it's NOT using https and therefore this isn't a TLS related issue, and therefore I've done all my checks against http.

Hi @APatchworkBoy


Can you tell me about your networking configuration? Are you NAT routed? Have you made any changes recently?

What is the output of the following (remove/obfuscate your public IP or identifying information) :

Code:
cat /var/cpanel/cpnat
Code:
curl myip.cpanel.net/v1.0

Hi Lauren - Yep, NAT config... recently switched to a Watchguard firewall, with sNAT / http-proxy / https-proxy rules in place... had some issues that resulted in us being delicensed as it stuck the webserver outbound on wrong IP which locked our license out the other day. Raised a ticket (cPanel Support ID #11821731) for it to be unlocked after the issue had been resolved at our end to shunt it out via the correct IP address...

Code:
#sudo cat /var/cpanel/cpnat
10.126.168.9 8x.x.x.52
Code:
#sudo curl myip.cpanel.net/v1.0
8x.x.x.52
All public IPs tally up to our licensed IP address etc...

Hi @APatchworkBoy

I can't help but assume that this is related as it seems like it's still a networking issue that you're unable to connect. Feel free to open a ticket though as I'm pretty limited to what I can check without access. I did look at the ticket and ran a quick nmap 80/443 over TCP both show as the only non-filtered ports which should be enough.

Issue resolved!

So, cPanel's MirrorSearch.pm in doing what it does sends some requests/gets some responses without http content-types set. Our firewall / httpproxy was set to deny all http-responses without a content-type defined.

Looks like this stops the ping test working within MirrorSearch.pm so upsets autorepair / updatenow / upcp.

Our infrastructure team have now switched this to allow instead of deny and all has sprung back to life. Screenshot attached should anyone else land here with Watchguard kit who can't find where we're talking.
