Update checks should use Happy Eyeballs, or other fallback.

Emby checks with www.mb3admin.com for updates, which is ofcourse dual stacked with IPv4 and IPv6 (awesome BTW). But if there is a IPv6 connectivity/routing issue it will simply fail/timeout, even if IPv4 connectivity/routing is ok, this can affect users with ISPs with poor IPv6 stability.

 

With happy eyeballs Emby can try both and use witch ever works first, or there could be even simpler logic to try any/all addresses received for the quarried FQDN (www.mb3admin.com in this case) if there was a failure/timeout.

Hi yes this makes sense. Thanks.

Hi yes this makes sense. Thanks.

I believe this could perhaps be an issue for ISP’s rolling out CGNAT too.

Any update?

Seems this also affects plugins and such when searching for metadata.

I think this is a good idea, but haven't had a chance to look into it yet.
