Error downloading subtitles

[Gabriele Gemmi]

Hi, since a few days I'm unable to download subtitles.

System.Xml.XmlException: Root element is missing.
   at System.Xml.XmlTextReaderImpl.Throw(Exception e)
   at System.Xml.XmlTextReaderImpl.ParseDocumentContent()
   at XmlRpcHandler.XmlRpcGenerator.DecodeMethodResponse(String xmlResponse)
   at OpenSubtitlesHandler.OpenSubtitles.LogInAsync(String username, String password, String language, CancellationToken cancellationToken)
   at Jellyfin.Plugin.OpenSubtitles.OpenSubtitleDownloader.Login(CancellationToken cancellationToken)
   at Jellyfin.Plugin.OpenSubtitles.OpenSubtitleDownloader.Search(SubtitleSearchRequest request, CancellationToken cancellationToken)
