[COMCAST] Steam downloads not hitting cache

[sircod]

System: unRAID 6.5.2

Issue Description: Steam game downloads are not hitting the cache.

First off, all this is working fine:

• Blizzard and Origin downloads get cached and work properly.
• Running "Resolve-DnsName steamcache.cs.steampowered.com" in powershell from another computer properly returns the steamcache server IP
• I see hits on the cache for "GET /serverlist/31/20/ HTTP/1.1" 200 785 "-" "Valve/Steam HTTP Client 1.0" "HIT" "valve1.steamcontent.com" "-"

Despite all that working fine I do not see any attempts on the cache for Steam game downloads.

Docker Container Output:

Any logs or commands I can try for more information?

Check this log to see what Steam CDN servers you are actually connecting to: C:\Program Files (x86)\Steam\logs\content_log.txt

You are probably connecting to a Steam CDN server that isn't in the list for the steamcache-dns container.

I had this issue where the Steam CDN load-balancer would dump me off onto a CDN hosted by Comcast. The resolution being to either forward the DNS for that CDN or blacklist it so that the Steam CDN load-balancer doesn't dump you off onto it.

This is actually discussed here: https://github.com/steamcache/steamcache-dns/issues/26

I believe the devs were looking into a redesign to handle this sort of issue.

Yeah, that looks like it. Mostly see references to cdn3-sea1.steamcontent.com but further down I see it is using edge.steam-dns.top.comcast.net

It's my understanding that this is now fixed. PR https://github.com/uklans/cache-domains/pull/19
