Stream skips back during live stream

[redgoalsuk]

Description

Some of our users are reporting that the live stream we provide skips back during the playback by itself and it happens more than once during the live stream

I have been unable to replicate the issue but I have asked one of our users to provide a debug log which is attached, I am not able to provide a live stream link for debugging as this is a commercial stream.

Steps to reproduce

Errors

"MediaSequence sync for main segment loader - received a gap between playlists"

this seems to be the point in debug log where the stream seems to "jump back"
