Loading subtitles from internet doesn't work

Steps to reproduce

This is what I did:

1. Search for a movie/TV show (eg, "breaking bad")
2. Choose HDToday source for the movie/TV show.
3. Choose a season (eg, season 3)
4. Choose an episode (eg, episode 1)
5. Choose Streamlare as source (by default it is Streamlare)
6. Click on "Source" in the player settings
7. Click "Load from internet" under the Subtitle section
8. Choose any of the given results
9. Click "Apply"

Expected behavior

The subtitle should be visible starting from where the video was left off.

Actual behavior

Subtitle didn't show up.

Other details

I tried loading subtitles from 3 different sources and none of them worked. I even tried syncing the subtitle thinking it would work, but no luck.

This issue is kind of similar to #31 but I don't know if they were loading subtitles from the provider directly or from the internet.

Acknowledgements

• I have searched the existing issues and this is a new ticket, NOT a duplicate or related to another open issue.
• I have written a short but informative title.
• I have updated the app to pre-release version Latest.
• If related to a provider, I have checked the site and it works, but not the app.
• I will fill out all of the requested information in this form.

Reproduce the issue on Android 11 using Cloudstream 3.1.5 at commit a58ca54, following the listed HDToday and Streamlare subtitle-loading steps. Start by tracing the player’s “Load from internet” subtitle flow and compare results from the three reported sources; done means a selected subtitle appears from the point where playback was left off.
