SOLVED: Subtitles out of sync, .SRT file, ok on PLEX/VLC

[Olick]

For some reason, my subtitles are out of sync on what i'm watching right now. On Plex (that I also run), it works flawlessly. It's also unsynced on JMP. My friend told me the same was happening in one of his anime, and changing the quality resynced them. This is an insanely huge problem for me that I never had before switching to JF. This is the first show where I have issues, my video/audio also freeze for 1-2s sometimes, like 4-5 times per episode. I don't know if it's related.

Bazarr or scripts to resync my subs are not a solution since it's perfectly working on all the other apps

I'm watching on my browser, but it's also unsynced on JMP.

Subtitles are in .SRT, and heres more info:

A user on reddit told me the solution:

One of those should work

disable this - Settings - playback - Prefer fMP4-HLS Media Container

dont use chromium based browsers if you are playing x265 content

3)force transcoding (for example lower quality)

No 1 and 2 should solve it. No3 sometimes help
