Domains How to troubleshoot domain not working?

Hi

I just reinstall my vps and i install Centminmod.

I create a vhost using my domain and i point from Godaddy an A record to my vps ip.

---

Do i have to setanything else on host other than @ ?

Now some times i can view the sample site and some not server not found

This was the reason that i rebuild the vps using the same ip.....

I check the block list in csf and my ip is not there and i can ssh to the server when my domain is not working !

I just notice that the phpmyadmin that i am using the ip is working when i can't access anything using my domain ....

How can i check where is the problem?

Thanks

 

I did the change a month ago

Yes i run the tests and all report fine

 

Yes i create the vhost domain and i upload my files to :

Code:

/home/nginx/domains/mydomain.com/public

Some times is opening and some not even if i use the www or not

 

removed.com

 

It was not working when i post it and after 20 seconds is working again

Damn.....

 

I will need to monitor the domain and not the server as the server always respond to ssh....

Also checking from online sites i am getting a message that is just me

I also disable the firewall to be sure....

Checking also the ppfpm logs i found that i reach max children already just creating 5 topics and checking phpmyadmin and apc admin page.....

That's why i ask from default to have much higher values on Centminmod installations

Only one user creating a few topics and got the first php-fpm limit

 

No other domains on the server

It is a vps 1gb ram only
