We have installed 3.4.2 on a Plesk server with NamesCo and the admin system is running very slowly.
It seems like a firewall issue and knowing how restrictive the NamesCo standard setup is only reinforces this idea.
Can anyone point me in the direction of the required settings to create a firewall rule on the Plesk box please?
I already have a set of stock IP addresses, etc. from NamesCo but as yet the problem hasn't been solved by them:
Allow outgoing to 126.96.36.199/24, 188.8.131.52, 184.108.40.206/24, 220.127.116.11/24, 18.104.22.168, 22.214.171.124, 126.96.36.199/24, 188.8.131.52/24, 184.108.40.206/24, 220.127.116.11, 18.104.22.168 on ports 80/tcp, 443/tcp
Thanks in advance for any assistance available.
