[Bug]: Playback Sessions from App not being Recorded

What happened?

So I have an issue that has occured when using the IOS app through testflight or through sidestore. The issue is I will do a listening session for a book lets say for example it starts at timestamp 1:00:00, I will listen for 30 minutes. Then I will pause/stop playback or change Bluetooth devices (headset to car or vice versa). When I go to resume the playback the app will not respond/crash and then switch to playing Apple Music instead. When I go into the app I see a websocket error and it acts like my most recent playback session did not happen it will start back at the 1:00:00 timestamp and I have to fast-forward back to where I was. I have enabled websocket support through my nginx proxy manager setup. The book can be downloaded or streamed does not seem to make a difference.

What did you expect to happen?

I would expect it to start playback from where I last left off.

Steps to reproduce the issue

1. Listen to book for awhile on IOS app
2. Pause playback
3. Resume playback

Audiobookshelf version

2.17.5

How are you running audiobookshelf?

Docker

What OS is your Audiobookshelf server hosted from?

Linux

If the issue is being seen in the UI, what browsers are you seeing the problem on?

None

Additional Notes

My setup for accessing it remotely is using my FQDN setup with Nginx proxy manager. I have websocket support, cache assets, block common exploits enabled in NGPM

So just experienced the issue again while on my home network. The playback went back about 20 minutes or so from where I stopped the playback. Pulled the daily and crash logs and uploaded them here

I will also try to remember to grab logs and record timestamps when it happens again. This issue is not 100% reproducible. I would say it happens like one out of every 5 or so playback sessions
