Network issues / Online games

[Megabust-1395]

I play every other Blizz game with out issue.

Starcraft(Now free version, even though I’ve bought the game)

I have nothing but connection issues with games, I drop regularly.

I have gone through everything… Firewalls, AV, Drivers, Network Adapters. I can not seem to fix this issue. I normally play USWest and have a good ping when I test that, once again every other game/app I use works great, no issues. Ive re-installed, both the app and the game.
Most games that I see listed are red or yellow, nothing ever green.

Besides giving up I am hoping someone has some suggestions? Windows 11.

oh well i had the same thing, my internet was kinda limited or something, 1megabit max. not goes upper. check in task manager whats your internet if its limited too, if yes then pay

but it can almost not drop if you change region to Asia (inbattlenet not gateway in sc) and turn on VPN, then almost no drops at all

so when I host game I get the “Due to your network configuration, you connection to other players must be routed via proxy…”

any way to fix this?

[CheatItUp-2187]

easy, your region is 100% Americas change it to something else.
Note: you can go back instantly if you agree with dangerous bugs on it

“Due to your network configuration, you connection to other players must be routed via proxy…”

@Leviathan-1945

Quick question. Under Options>Network, do you have “Prefer port 6112” checked?

@Leviathan-1945

If you uncheck it, you’re telling the game server that you are willing to use any port in the range to directly connect to the other player. With more ports available, there’s a higher chance the server will find a matching port between you and your opponent(s). If one is found, you’ll be linked directly together (P2P), thus not needing the proxy.

Conversely, by having it checked, you’re telling the game server that you will only use that one port to directly connect to another player. This has a far less chance that the server will be able to find a matching port between you. If it can’t, your game will be routed through a proxy server.

You mention that you have an unconventional network setup. If you have security/firewall settings that you must keep in place, it’s possible that due to the restrictions those place on ports, you’re only option is to play through a proxy. But if you are the admin of the network, you should be able to set it to allow SC to use ports to directly connect to other players.

also, perhaps try these threads:

"Due to your network connection, your connection to other players must be routed via a proxy server, which may add latency"

this was my issue … By default, some firewalls rewrite the source port on all outgoing packets. Many operating systems do a poor job of source port randomization, if they do it at all. This makes IP spoofing easier, and makes it possible to fingerprint hosts behind the firewall from their outbound traffic. look up static port NAT pfsense [Edited by Blizzard] This thread has been inactive for some time.

I found the problem: I didn’t got any error message but this was it, even the same App. After using the diagnose tools for connections I realized that the traceroute was broken so something was interfering with the firewall or ports, after looking at older post, that didn’t show in google, I tried the solution and it worked. Had installed the mentioned app a week before installing SC:R Also blizzard has some interesting tools to help diagnose the problem:

That proxy message is quite useful. If you haven’t already, take a look over Blizzard’s connection troubleshooting guidance:

https://support.blizzard.com/en/help/article/146644

If you have already forwarded the ports and still receive this message, opening the ports has not established a direct connection. That points to something else in the network path, such as the router’s NAT behaviour, CG-NAT or another network restriction. The router manufacturer or ISP would need to confirm which one applies.

You should first reach out to your ISP to see if they are blocking these ports. If they are, they should be able to provide guidance on what you or they can do.
