ERR_NAME_NOT_RESOLVED on subdomain

[thepascalboy]

Hello,

I have my sentora server already running for a month but now I just want to add a subdomain for my owncloud. I added 48 hours ago my subdomain and also added it in the CNAME. But I am almost always getting the error: When I try to get on my subdomain. It works only 99% of the time..
And the best part is that I cant find any problems in the log, also my friends cant visit the subdomain but the head domain is just working fine.

I am running sentora 1.0.0 on CentOS 7

Well first what dns servers are you using? likely not those on sentora panel.

So you need to add the dns entry in your registrar or cloudflare if you use that.

I use the sentora dns server:

thepascalboy on your domain registrar what nameserver entry do you have?

Thanks for the tip, it was my second nameserver. The second name server is running somewhere else beacuse my registar dont want me to use 2 nameservers on 1 ip. But I tought it takes only nameserver1 for my dns but I also need to add the CName by my second nameserver otherwise it crashed like this, that was my problem.
