Domain that you have provided is not configured as rDNS for your server IP. [404]

Support and Discussion
1

Hi, I’m new here, I’m facing error- Domain that you have provided is not configured as rDNS for your server IP. [404] in version 2.3.5 [Setup Wizard.]
In previous 2.3.4 the hostname and mail server was configured correctly and working without any issues. But after updating to new version no mail can be sent. Manually issuing MailServer ssl works but crashes again within 1/2 day. Changing the nameserver in resolv.conf also doesn’t work.
Someone help me please…

Can you confirm if rDNS is properly set?

3

I think I found the problem, can you upgrade your server and try now? it should be OK.

4

thanks for respond, yes my rDNS set properly.

Issue mail server ssl now, upgrade your server and it should be fine.

I have issued mail server ssl last night and also upgraded cyber panel. it’s working… but I don’t know how long it will be work? because I have issued ssl 3 time from last upgrade. The Setup wizard still showing error.

You need to upgrade now as I’ve pushed some commits to fix this.

8

thank you very much, allow me sometime to update and check it.

After upgrade last commits onboarding setup still showing Domain that you have provided is not configured as rDNS for your server IP. [404], last night issued ssl has gone. if i sending any mail it showing ‘can’t connect to server’

Issue mail server ssl now, upgrade your server and it should be fine.

That is why I said this above, because your rDNS is cached in DNS, just issue mail server SSL now.

11

RDNS has been set a long time ago. Nothing has been changed anew. Even if it is cached, there should be no problem. Everything was fine before. The mail score was 10 out of 10. However, I issued SSL again. Let’s see if there’s a problem?

It should be fine, please report there tomorrow.

What I realized after a few days of use is that mailserver ssl is lost when updating and rebooting the server. I updated the last commit but still gives an error from the setup wizard.

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