Hi there,

For some reason since 2024-12-21 15:00 ytdl-sub is getting 403 errors when syncing youtube channels. It was working fine for ages, then the last couple of days I noticed no more youtube videos are syncing, checked the logs and saw this;

[ytdl-sub] The following error occurred for the subscription History Channel:
Traceback (most recent call last):

Not sure if that is enough to go on, if not I can add more... Interestingly I can download the video using the same url you see in that snipped using yt-dlp outside of ytdl-sub, so I think something happened to ytdl-sub in the last update perhaps?

Any ideas?

Syncing channels on Odysee.com work fine still though - thought that might be useful to add 😅

[christiansacks]

I think it's related to IPv6 - looks like maybe my ISP borked up something in their IPv6 somehow, and I had to use --force-ipv4 for yt-dlp for it to work, but I don't see any way in the yaml to do that for ytdl-sub, how would I pass --force-ipv4 to yt-dlp within the yaml?

[Jerroder]

It is related to IPv6, passing -4 or --force-ipv4 works for yt-dlp. However I could not find how to add those args from ytdl-sub directly but adding source_address: '0.0.0.0' to ytdl_options works for me.

ytdl_options:
  source_address: '0.0.0.0'

[christiansacks]

Aha! I think I just figured out where to put it;

~ > head -5 .config/ytdl-sub/tv_show_subscriptions.yaml
__preset__:
  
  ytdl_options:
    source_address: '0.0.0.0'

This seems to be working 🤞🏻
