Issue Downloading Overwatch

[TheGrandPackard]

Might have answered my own question by RTFM.. Looks like steamcache does provide an sniproxy container:

docker run \
  --restart unless-stopped \
  --name sniproxy \
  -p 443:443 \
  steamcache/sniproxy:latest

I can give that a shot

Also, when I was troubleshooting it, I believe the nydus.battle.net was getting redirected to HTTPS which would obviously bork the caching capabilities. I don't recall this being an issue a few months back when I ran the same setup.

Hey,

Can I ask where you're located geographically?

We also ran a fairly large LAN this weekend in the UK, and Battle net was fine so I suspect this CDN alias is geographic, and should probably be excluded if it is redirecting to https.

[TheGrandPackard]

Southern California, just north of Los Angeles (USA). I set up the DNS forwarder on steamcache-dns to my router, which should be pulling DNS from the ISP via DHCP (Spectrum/Time Warner Cable).

I wouldn't be surprised at all if it was a geo-dependent which means that there's not a clean/one size fits all solution. Fortunately I didn't waste too much time in finding which domain it was with tcpdump.

I'll upload the error message from battle.net tonight and it can at least be noted if it comes up in the future with a workaround.

Just to check, were you running SNIProxy or similar on all caches you were running?
This allows SSL to be transparently proxied. It does mean that those connections cannot be cached though, but at least downloads would work.
Potentially that domain has partially migrated to SSL for the US only?

[TheGrandPackard]

I don't know whether or not I was running SNIProxy as I was using the steamcache docker containers, but I only had port 80 bound, so I assume that it wouldn't work for HTTPS anyways. Do you know if that's a supported feature of steamcache, or do you use something else that supports it?

I was running the steamcache-dns docker container with the following config:

docker run \
--name steamcache-dns \
-p 10.0.1.27:53:53/udp \
-e STEAMCACHE_IP=10.0.1.27 \
-e UPSTREAM_DNS=10.0.1.1 \
steamcache/steamcache-dns:latest

and the steamcache docker container with the following config:

docker run \
  --name steamcache \
  -v /cache/steam/data:/data/cache \
  -v /cache/steam/logs:/data/logs \
  -p 10.0.1.27:80:80 \
  steamcache/generic:latest

Ah!
steamcache.net also maintain a container for sniproxy: https://github.com/steamcache/sniproxy
This container is mentioned on the readme for steamcache/generic, under "Origin / SSL"

[Lepidopterist]

So, it looks like if this CDN hostname is included in the cache, you'll need to run sniproxy to pass through https.

We'll validate the info from the logs from our last event, then decide how to handle it here.

Thanks!

I had the same issue yesterday with the overwatch, even tho I use the sniproxy container.

[adamradocz]

I had to forwarding the port of DNS, now it's working.

[TheGrandPackard]

I was able to test this with the sniproxy running and it works as expected. It's strange that a few months ago it wasn't necessary, but i'm glad it's there and getting it done for me now.
