Can you do one last thing and share logs from CyberPanel main log file ?

I’ve tried to reproduce your situation and these are my logs

[02.13.2024_18-25-13] Postfix Hostname: cl.cyberpanel.net. Server IP 95.217.248.69. rDNS: cl.cyberpanel.net, rDNS check 1

You can run on cli

Then run

cat /home/cyberpanel/error-logs.txt

then share logs of this log command.

So I keep seeing this error, can you open a ticket here with server logins: https://platform.cyberpersons.com/

then mention ticket id here.

24

To create ticket in support departments you can purchase CyberPanel Cloud Support plans.

I cant create ticket. Is it Paid? My all server have same issue.

I have skipped Additional Features “Skip rDNS/PTR Check (If you don’t want to use email service on this server)” then logs showing like…

@usmannasir i face the same issues with rdns…
The rdns is setup correctly, and i also check with ‘dig -x’, but in the setup page from cypberpanel it always return 404( Domain that you have provided is not configured as rDNS for your server IP. [404] )

What should i do?

Panel Version: 2.3.5 (c97df70156acd8d6a005d7b10e9f6a0aaf900c23)

Thank you!

27

I am still having the same problem. But I have adopted some trick to solve it. Completed setup by skipping Mailserver. Later I did separate mailserver ssl issue. But the problem is that every time I reboot the server, the mailserver ssl is lost. As a result, every time after rebooting the server, doing a separate postfix restart (systemctl restart postfix), then everything works fine.

Also noticed after 2.3.5 version upgrade no error log is coming in admin profile default mail.

28

Well if the problem is only at reboot, will not be much trouble, but does the ssl autorenew itself?

For example, i do as you said, and skip mailserver then issuse ssl, the ssl have 3 month lifetime, does it after 3rd month get renewed? or i have to issuse again ssl?

Thanks for tip, but i’m already use Cypberpanel for like 2 years, and everything went smooth till last update.

29

Good question. I also faced this problem on upgrade to 2.3.5 version. Since it hasn’t been 3 months, I can’t tell you exactly. But I hope that connected ssl will autorenew normally.

Hi,
Me too, I’m facing the same issue with my server. I was able to upgrade some VPS before without any issue, but this time I got that rDNS error even thought I’m sure it is setup correctly, the only difference here it is a dedicated server not a VPS (I use Hetzner). Could you please fix this?

31

Update (Resolved):
I was able to fix the issue by editing the /etc/hosts file and adding the correct hostname to it. This was on a dedicated server running CentOS 7.
I observed that after running the command:
ping example.com
I noticed that the hostname was incorrect because the output appeared like this:

PING localhost.localdomain (127.0.0.1) 56(84) bytes of data.
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=1 ttl=64 time=0.026 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=2 ttl=64 time=0.023 ms
64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=3 ttl=64 time=0.024 ms

The problem was with the localhost.localdomain section (which may vary in your situation), but this is supposed to be the hostname, so I modified the ipv4 part like this (example.com should be substituted with your hostname):

# IPv4
127.0.0.1 example.com example
127.0.0.1 localhost.localdomain localhost example.com
127.0.0.1 localhost4.localdomain4 localhost4 example.com

After saving the hosts file and restarting the server, I used the ping command to verify everything was working correctly. When I reran the setup wizard, it completed successfully!
I hope this can help you.

32

Did you added “127.0.0.1 example.com example” above or edit an existing line?
Because I tried by modifying the existing line. Then the server became very slow and was about to shut down. There is no section called IPv4 on VPS server in this file.

33

Can you copy & paste the content of your /etc/hosts file? Just to clarify: My server is an old one using CentOS 7, from Hetzner, maybe things are different for you. I think I should mention the OS in my previous post.
