This was a hard weekend for Stremio as the OpenSubtitles API was blocking our servers due to a recent change on their side and we received a huge number of reports from our users about it.
We first became aware of this on friday and contacted OpenSubtitles support, a fix could not be provided on that day though and OpenSubtitles support was unavailable through the weekend.
We are happy to announce that today the issue was fixed and everything should be back to normal!
