Update 64 - CloudFlare + LVE Bad Gateway

[Jamira40]

Hi,

Just in case somebody else has the same issue using CloudFlare + LVE and you can't see stats or any settings because CloudFlare returning 502 Bad Gateway.

The issue is in the way that cPanel changed the handling of Proxy Subdomains.

Open /usr/local/cpanel/whostmgr/docroot/cgi/CloudLinux.cgi and find this lines

1. sub _checkReferer
2. {
3. my $protocol = (exists $ENV{ HTTPS } && $ENV { HTTPS } eq 'on')
4. ? 'https' : 'http';
5. my $ip = $ENV { HTTP_HOST };
6. unless ($ENV{ HTTP_REFERER } =~ qr/^$protocol:\/\/$ip/) {
7. sendError('BAD REFERER', 0, 1);
8. }
9. }

You have to comment out line 6 7 and 8.
There is something messed up with $protocol or REFERER I did not check them.

Of course, this will not last forever (maybe a minute) because it will check and modify that file again. But at least you know what is causing this issue and it's not CloudFlare issue.

Hello @Jamira40,

It looks like CloudLinux has an internal case open (WEB-542) to investigate and determine if this is a bug in their LVE Manager plugin. We'll monitor the case and update this thread with more information once it's available.

Thank you.
