Fix: Plex Fast Forward and Skip Back not working

You will have to check with different combinations here. Try disabling Direct stream enabled and direct play enabled and vice versa. You can also try disabling them both at once.

Delete Cache files

Deleting cache files can speed up the playing process. Due to prolonged usage, plex may create larger no. of cache files resulting in this error.

In windows:

1. Open the Run box and enter the following path into it.

   %LOCALAPPDATA%Plex Media ServerPlug-in SupportCaches

2. Click on enter and open the path.
3. Delete all cache files listed there.
4. Restart your Plex client and check.

In Mac:

In case you are using Mac OS, then you will have to follow these procedures instead.

1. Open Finder and click on Go > Goto folder option.
2. Paste the following location into it:

   ~/Library/Application Support/Plex Media Server/Plug-in Support/Caches

3. Delete all files and folders within it.

Now restart the plex client and check if the problem is still present.

Check the Subtitle file

Some people have also reported that disabling the subtitle altogether solved the issue for them. This issue could also result because of using incompatible subtitle files.

1. Go to the settings option on your plex client.
2. Under video see if you could find subtitle sections.
3. Disable it and check if the fast forward or skip back function work properly.

If working, then you will have to find ways to load a different subtitle file for your media.

Check the actual media file

The next thing you want to check is the actual media file. Because some times the actual media file might be having some problems resulting in this issue. Check if you can play the file without any issues with a media player like VLC locally.

If the file is having the same problem there, then you might want to check the file or consider downloading it again or copying it again from the original source.

Update the Plex server version

Sometimes, if you are using an older version of the Plex server, then you might find this issue. Because, if you check the release notes for the latest version, you will often find these bugs being addressed. So the best idea is to take a backup and update the version of the Plex server to the latest one.

Once you have updated, check if the problem is still present in the media player. If you have found any issues after updating, you can revert back to using the backup.

Conclusion

So as you can see, these were some solutions that you can try to fix Plex Fast Forward and Skip Back not working issues on the playing media. One more thing to notice here is if you are using weaker hardware to host a higher resolution media, then you may have some bottlenecks on the server end. So it is good to also check the resource utilization on the server end as well.
