Changing DirectAdmin port & CSF problems

[MackSix]

Is there anything I should do when I change DirectAdmin Port other than just change the port number in the config file and restart DirectAdmin?

I found that I should add the new port number for JetBackup and restart it.

The thing is, I am now having an unusual amount of problems with CSF giving me the message:

"Security Error: No valid session key
Information saved to [/var/lib/csf/da1674758841.error]"

I have seen this before a few times and a logout/login fixes it, but now it is very problematic.

Sometimes the firewall configuration screen loads a blank page.

Right now I am looking at CSF home screen and I can refresh the page and it gives me a lot of the above error messages. About every third time I refresh screen, it gives me that error message, then the next refresh I see the home page just fine. I am doing nothing but just refresthing the screen.

UPDATE: It looks like the Environment data is showing the same IP except for the last number is 4 instead of 5.

To disable DirectAdmin session checks, create a touch file called /var/lib/csf/csf.da.skip

I see, those are Cloudflare IPs. I unproxied the URL to DA, thinking that Cloudflare was the problem and it is still picking up the Cloudflare IP. I will have to live with it to stealth the IP or put my website on a different IP on the server.
