Server Not Accepting Incoming Connections (Random)
I am having a strange problem with my server. I just migrated away from Plesk in the last few days and installed WHM/cPanel on a VPS with 4 cores, 8GB RAM and CentOS 7. The server will, at random times, suddenly quit accepting incoming connections for all services (WHM/cPanel, HTTP, HTTPS, SSH, etc.) and will recover a few minutes later or sooner if I restart firewalld. The fact that it recovers after restarting firewalld might be a coincidence since I've even turned off firewalld and the problem persists. There are less than 20 accounts and all low-bandwidth sites. I own the physical server and all of the other VMs aren't experiencing the same issue so I know it's not the physical connection.
I could really use some suggestions on what to check. This is getting frustrating.
Thank you,
Chris

It *seems* I may have fixed it. My NIC was configured for both IPv4 and v6. I don't have any IPv6 addresses assigned to me at the datacenter so I disabled it. I haven't had a problem in at least 14 hours that I'm aware of. Chris 0 -
