Proxied stream keep disconnect intermittently, need advice on configuration

Question

I'm using mediamtx to pass an HLS IPTV stream to my local server so that I can view the stream via browser. Everything works well but there is one particular stream which is not stable and keep disconnecting. Here is the log from mediamtx that kept repeating.

I've tried to edit the HLS segment duration to longer time as shown in docker-compose file below:

version: '2'
services:
  media-server:
    image: bluenviron/mediamtx:1.8.0
    environment:
    - MTX_PROTOCOLS=tcp
    - MTX_WEBRTCADDITIONALHOSTS=192.168.1.1
    - MTX_PATHS_PROXIED_SOURCE=https://external.stream/index.m3u8
    - MTX_PATHDEFAULTS_SOURCEFINGERPRINT=XXXXXXXX
    - MTX_HLSSEGMENTDURATION=7s
    - MTX_HLSPARTDURATION=1s
    - MTX_API=no
    - MTX_METRICS=no
    - MTX_PPROF=no
    - MTX_RTSP=no
    - MTX_RTMP=no
    - MTX_WEBRTC=no
    - MTX_SRT=no
    ports:
    - 8888:8888

However the issue still persists. The same stream is working fine on Kodi player. Obviously this part of the message ERR [path proxied] [HLS source] next segment not found or not ready yet is the biggest clue. Is there any configuration I can set to prevent it from disconnect the proxied stream when server is not responding? Any help is appreciated. Thank you.
