cPanel update failed
Answered
I have cPanel version 11.110.0.50 and I'm trying to update it due to the vulnerability (CVE-2026-41940), but I haven't been able to. I get the following error:
[2026-05-02 17:05:57 -0600] ***** FATAL: Failed to stage “cpanel changes” because of an error: 404 - 404 Not Found - HTTP ERROR ...propagated at /usr/local/cpanel/scripts/updatenow.static-cpanelsync line 47335.

Could you help me update?

Hey there! I would like to see a bit more of the error log as that particular section isn't helpful. Could you share the entire log, even if that means copying it to a pastebin somewhere and sharing the link?

Thanks, I was able to resolve it. I had to disable the firewall and install epel, and then I was able to update to .97.

alansplash - it's almost certainly a networking issue of some sort on your side, as your output indicates it can't reach any of the cPanel mirrors. If you've already tried disabling the firewall can you check with your host to see if there may be other issues?

I can ping all the IP addresses all okay, is there a specific port the update uses ?
Thanks
0 -
There aren't any special port requirements as they just use 80 or 443 to connect. Can you telnet to a few of those IPs over port 80?
0 -
Yes, that looks okay:
# telnet 89.222.122.161 80
Trying 89.222.122.161...
Connected to 89.222.122.161.
Escape character is '^]'.
Connection closed by foreign host.

Could it be that the IP addresses my system is trying to use are wrong ?
0 -
Those IP addresses seem correct as they match what my system is pulling at this time.
0 -
should i just open a ticket ?

FYI this fixed the update above, I had update the current set version
# whmapi1 set_tier tier=11.110
