Linked domain unstable?

After the migration, my linked domain seems unstable. It worked fine at 8.00 CET, redirected to http://error404.000webhost.com/? at 9.00 CET, worked fine again at 10.00 CET and is again redirected to http://error404.000webhost.com/? at 11.00 CET.

https://nicholashjelmberg.000webhostapp.com/ has worked fine all the time while nicholashjelmberg.com has not. All status pages look fine and shows no errors.

However, I did run a test on http://dnscheck.pingdom.com/ and got the result below. Is it an error with 000webhost or my domain registrator? Would a service like Cloudflare help mitigating this problem?

ns01.000webhost.com.

… and my domain works again (11.30 CET) although the DNS check still reports the same error. Any insight in the cause would be welcome.

You haven’t mentioned your linked domain but those errors are common on all linked domains so just ignore them, give it 48 hours after linking and give your computer DNS cache/ browser cache a clear too.

I mentioned my website nicholashjelmberg.com or do you refer to anything else as “linked domain”?

I’ll see if the link is more stable after 48 hours. It has worked fine the last few hours.

Totally blind here sorry.

Stable here!

Thanks for confirming!
