Sonarr limiting dognzb api

I was wondering why some older results found by me on dognzb were not getting picked up on sonarr. The debug log gives:
https://api.dognzb.cr/api?t=tvsearch&cat=5030,5040&extended=1&apikey=&offset=0&limit=100&rid=24493&season=1&ep=1

which gives 0 results

When I change the retention limit in sonarr nothing changes, the limit stays the same.

Also, when I try to test the connection to https://api.dognzb.cr it fails! So I can change anything about that!

Any Ideas?

Their API is still down (if you do a search on these forums you will find many threads discussing this).
