failed to download subtitles

I have uploaded my kodi log file here: https://paste.ubuntu.com/23106935/

No matter what add on I use or which movie I try or which subtitle file I select, they all end the same way: "failed to download subtitle" with a red circle and a white 'X' in it.


(hopefully this link is to a screenshot of the error, in the bottom right hand corner of the screen.)

I would be grateful for any help in resolving this as I have tried several different English language subtitle providers (only really for forced parts or non-English spoken parts)

When I download the subtitle files on my computer, then copy them across to the subtitle folder I have selected, it works fine when I select that subtitle file in kodi.

I think it might have something to do with the fact that many subtitle providers are zipping their files, instead of keeping them in a subtitle file format, as I noticed this then it first stopped working months ago and I went to my computer to get them manually.
