Steps to reproduce

As written in the title the Import subtitles from internet feature is not working properly. See when I try to use it it works in some cases but not it most like in big titles One Piece, Ironheart , The Flash ,etc . There are many examples like that in which this feature does not works , I have seen in many other apps the same feature works for these titles. Everytime I click on it it show errors like "Null subtitles". Kindly solve it . I am using this in Android tv.

Expected behavior

When I use the feature Import subtitles from internet it should work and give me subtitles like for big titles like one Piece and more.

Actual behavior

It just pop up some errors like "Null subtitles" , time out (my internet is stable) and many other errors.

• I am sure my issue is related to the app and NOT some extension.
• I have searched the existing issues and this is a new ticket, NOT a duplicate or related to another open issue.

• I have updated the app to pre-release version Latest.
• I will fill out all of the requested information in this form.

Start by reproducing the Import subtitles from internet flow in Cloudstream 4.5.4 on Android 9 with the listed titles, and capture the logcat output because the report provides none. Trace whether the failure is consistent across titles and subtitle sources; done means the feature returns subtitles without the reported Null subtitles or timeout errors.
