I found that the website yt1s.com, in the US, UK and Philippine, indicates that the page is out of service as of August 1, 2020. I later found out through chrome's network detection that the page yt1s.com has a 302 redirect. in these areas it redirects to the website us.yt1s.com, thus suspending the web service. I then found out through a Google search that yt1s.com has changed to the domain name yt1s.icu after 2020. yt1s.icu website has been able to provide normal web services so far. So I changed the code on line 126 [addButton.href = "//yt1s.com/en/youtube-to-mp3?q=" + encodeURIComponent(location.href);] to [addButton.href = "//yt1s.icu/zh- cn?q=" + encodeURIComponent(location.href);]. I hope my comments will be helpful to you and I look forward to your adoption of my comments and your reply.
