Example:

curl --interface 11.22.33.44 http://alltime.pp.ua/

wget --bind-address=192.0.2.116 http://alltime.pp.ua/

Go to your WHM –> Home –> Software –> MultiPHP Manager

You should be able to resolve this by changing the domains to use an available version of PHP, or by installing the missing PHP versions.

You need to either install missed PHP version or set it to inherit

whmapi1 php_set_vhost_versions version=inherit vhost=domainname.com

Check if you can reach a remote server

dig a gmail.com

If this timeouts then try over one of dns resolver directly

; <<>> DiG 9.11.4-P2-RedHat-9.11.4-26.P2.el7_9.2 <<>> @8.8.8.8 a gmail.com

;; global options: +cmd
;; connection timed out; no servers could be reached
