HTTP 401: Access denied error using onlyfans_extractor.py

Throwing this error when I try download a PPV video in DMs. C:\Users\ahnad\Downloads\onlyfans_cdmpool>python3 onlyfans_extractor.py --message-id 10820334152156 [*] Fetching dynamic rules… =========== Message 10820334152156 =========== [!] OnlyFans API /api2/v2/messages/10820334152156 → HTTP 401: Access denied. I refreshed my API key and tried the new one in the .json, and I also re-checked that I'd copypasted the cookies in correctly. Not sure what the problem is.
