Seedbox is blocked

My seedbox adress http://psb45087.seedbox.io/ is being blocked
and i have added both seedbox.io and psb45087.seedbox.io to whitelist.

The error i get is: ERR_NAME_NOT_RESOLVED

This does not indicate that the domain is being blocked. It may indicate that Pi-hole cannot resolve that domain name to an IP.

Run this dig command from Pi-hole and see what returns:

dig psb45087.seedbox.io +short

In my case, Pi-hole returned 185.45.195.172

Then, from a connected client, run this command and see what returns:

nslookup psb45087.seedbox.io

This is what it replies:

root@raspberrypi:/home/pi# nslookup psb45087.seedbox.io
Server: 127.0.0.1
Address: 127.0.0.1#53

Non-authoritative answer:
Name: psb45087.seedbox.io
Address: 185.45.195.172

That is one of the two requested outputs, and shows that Pi-hole is not blocking the domain. The other output will show what the client is receiving in response to this request.

And suddently it works.
I dont get it.
