    Hey there! I'm sorry to hear about the cPanel restart issues. Do you see anything interesting in the cPanel log file at /usr/local/cpanel/logs/error_log? That is the first place I would check to find more details about this issue. For the Apache status issue, are you seeing that problem in WHM >> Apache Status? If so, what does "apachectl status" on the command line show?

    @Lor I do have the issue. I've tested all TCP ports that cpsrvd is currently listening, also I' Steps to reproduce these tests: 1) netstat -nlp | grep cpsrvd tcp 0 0 0.0.0.0:2087 0.0.0.0:* LISTEN 4016/cpsrvd (SSL) - tcp 0 0 0.0.0.0:2095 0.0.0.0:* LISTEN 4016/cpsrvd (SSL) - tcp 0 0 0.0.0.0:2096 0.0.0.0:* LISTEN 4016/cpsrvd (SSL) - tcp 0 0 0.0.0.0:2082 0.0.0.0:* LISTEN 4016/cpsrvd (SSL) - tcp 0 0 0.0.0.0:2083 0.0.0.0:* LISTEN 4016/cpsrvd (SSL) - tcp 0 0 0.0.0.0:2086 0.0.0.0:* LISTEN 4016/cpsrvd (SSL) - unix 2 [ ACC ] STREAM LISTENING 397830 4016/cpsrvd (SSL) - /usr/local/cpanel/var/cpwrapd.sock unix 2 [ ACC ] STREAM LISTENING 397831 4016/cpsrvd (SSL) - /usr/local/cpanel/var/cpauthd.sock unix 2 [ ACC ] STREAM LISTENING 397832 4016/cpsrvd (SSL) - /usr/local/cpanel/var/cpdoveauthd.sock unix 2 [ ACC ] STREAM LISTENING 397833 4016/cpsrvd (SSL) - /usr/local/cpanel/var/cpdoveauth_domainownerd.sock 2) nc -vz 127.0.0.1 2086 Ncat: Version 7.50 ( Ncat - Netcat for the 21st Century ) Ncat: Connected to 127.0.0.1:2086.

    @heinickenb - are you saying that cPanel is also reporting as down on your side as well? If you run "/scripts/upcp --force" does that correct the issue?

    Unfortunately it doesn't !!! By the way our server is running CENTOS 7.9 and WHM & Cpanel @ v92.0.9 Still receiving those alerts:

    Thanks for that screenshot. The monitoring tools just think cPanel isn't functioning correctly, which is must be as you're logged into WHM. If this only happens with CSF enabled it seems like there is some odd behavior with the firewall. Can you make sure all the necessary ports are opened for traffic in CSF that are outlined in our guide here?

    CSF isn't part of cPanel as we don't maintain or distribute that software, so I can't say for sure if an update we performed would have had a negative interaction with that. If things work with CSF disabled it might be best to reach out to their support at ConfigServer Technical Support to see if they are aware of any issues with that tool recently.

    By the way, this problem started about a week ago

    On my server the problem disappeared about 2 days ago. Looks like after last update. I did nothing. But WHM Apache status still not working: Apache server status for server.xxxxxxx.com Failed to receive status information from Apache.

    Would that server happen to be running Litespeed? If so, it wouldn't be able to pull the Apache status. Does the status work if you disable the CSF firewall temporarily?

    I'm sorry. It's still here. But I found when it started. The problem started after I installed OpenVPN access server. I uninstalled it after 3 weeks, but cpsrvd monitoring and Apache status still not working. Looks like OpenVPN did some changes in firewall config. I checked few times all CSF settings but couldn't find the reason.
    Does the status work if you disable the CSF firewall temporarily?

    Yes. Apache status and cpsrvd monitoring works fine when CSF disabled.

    I run CSF on my personal machine and I haven't come across this error with the Apache status. It would be best to reach out to the CSF team directly at ConfigServer Technical Support to see what their thoughts on this issue would be.
