I'm having the exact same issue. I've figured out a temporary workaround, though. If you look at the URL, it doesn't say https://Anime-owl.net/watch/show/episode, it says https://portablegaming.co/watch/show/episode. Replace "https://portablegaming.co" with "https://anime-owl.net" and you should have a usable temporary if annoyingly tedious fix. Hopefully this gets resolved soon... Source: about 1 year ago

We have a plan to download files from torrent sites like nyaa and add them to our streaming site animeowl.net .But the biggest challenge so far is to be able to map the data on nyaa (usually only data is the torrent file name) with MyAnime list info. Does anyone have an idea how can we do this automatically? Source: over 2 years ago

I agree, to keep our site animeowl.net alive, we also put a lot of effort into hiding, but let's say we also learned it the hard way. lol. Source: over 2 years ago

In episode 2677 at some where between 8:00 to 8:30 seconds in, a marine soldier tries to contact spandam via a den den mushi, but that den den mushi has mr 3 written on it! Is it the same for you? I'm watching on animeowl.net with adc-heaven fansubs so check if it's the same on other websites. Anyways, what do you think this could mean? Source: over 2 years ago

First thing I tried was typed card.io in my web-browser to see whether it would bring me to a website associated with this game. Source: almost 2 years ago
