Hello

We have a client that is unable to load any URLs on one of our servers. They have no problem with any of our other servers. We are running ConfigServer Security & Firewall - csf v2.90. The IP is not in the Deny List. We are not running APF? Does anyone have any suggestions? Where else might we try looking?

Thank you.

What is he seeing in his browser when he tries to connect? Error messages can go a long way to resolving the issue. Do you have mod_security, mod_evasive or DDoS installed? Is he connecting direct or through a proxy? Has he tried using a proxy to confirm he can connect?

1) Did you make sure CSF is not the culprit ? What happens when you stop it ?

2) Did you check in the Host Access Control (block IP access) in Security Center that his IP is not listed there ?

3) Ask for a traceroute ?

Good luck :)
