System (please complete the following information):
There's an issue with the web server configuration right now that's causing those errors. We don't plan on moving to locally hosted fonts because it needlessly balloons the web client size, but this was added with configurability in mind. There has been a config file for the web client since 10.4.0 and it now includes a section to load fonts as desired. This will probably extend to the fonts used by SubtitlesOctopus for SSA subtitles at some point as well.
I second this, it is a bad idea to use online fonts. It defeats the purpose of self hosting. I also saw requests from Google Static (gstatic.co m) being blocked by uMatrix.
This has been fixed for 10.7.
