I suggest you to wait. It’s forum not 24/7 live support. It’ll take a few hours to find an answer. The time you’ve created a topic is when most of people here are sleeping.
Usually this problem happens when the SSL details update. You should wait up to 72 hrs for the thing to actually work.
If you are using the InfinityFree SSL certificates, I suggest you to re-upload the ssl cert and pr key. This worked for me.
Another tip is to change your nameservers to: ns1.epizy.com and ns2.epizy.com
That’s very odd. Because someone else has reported same issue plus I can see nameservers are set to our nameservers but some dns looker ups don’t show it points to right name servers.
Probably an issue at our end. I suggest you to change your nameservers to ns1.byet.org and ns2.byet.org and see if works?
This domain name does not appear to have any nameservers right now. Please check with Freenom whether your domain name is active and configured correctly. This is not something you can fix on the hosting side.
