Wait, I think I solved the issue. Thanks for your help anyway! Have a great day

I've been having a similar problem. Very frequently I have been getting the same error message telling my that the link could not be found. It has only been doing this with YouTube links so far. What I do is copy the video link to the link bar and it tells me the link couldn't be found. It only does it with some links. But as time goes by, it has been getting worse. I don't know what's causing this. There is one thing that I do as proof that it could be a bug. I use Google Chrome browser. So whenever the link fetcher does this, I duplicate the tab about seven times. As I do this, I check all tabs to see if the link works on one of them. Well, I tried and there was one tab that worked with the same link I used on all other tabs in which the link didn't work on.
