Sub domains not working after update

[Karl1]

Hi,

I logged to WHM and there was that notification on the right top corner saying "You need to reboot to finish update".

Also had a notification from cpanel/whm with:
"The system’s core libraries or services have been updated. reboot the server to ensure the system benefits from these updates."

I did it and after that the sub domains are not working at all. When I visit it points to the defaultwebpage.cgi page

Please help, as I am with server down

 

[Karl1]

one other sub domain gives message:

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.

I know this is a very basic response, however, have you tried to hard reboot your server?

You could also do a "dig" to check DNS.

Example command to run from SSH: dig +short subdomain.example.com

 

[Karl1]

this is weird.

the dig results always was correct showing same IP as the main domain.

But I've rebooted it more than once before I created this post.. and it didn't work before.

Anyway, it is working now.
Thanks (!)

Hey Karl,

Good to hear your back online

Hello,

It's interesting that it was only the subdomains that were not loading. Do you notice any output to /usr/local/apache/logs/error_log at the time you encountered the 503 error code in your browser?

Thank you.

Hi, yes, still not solved this, and it happens only with sub domains.
