Me and ma homie have lost hope in trying to resolve his Network Issues in CS

[Shotgunnn]

After 2 days of edging, 6 tutorials, steam support, screaming, mental breakdowns we have made 0 progress.

The same message keeps popping up: "Matchmaking Failed, Failed to reach any official servers. There might be a problem with your internet connection or firewall configuration. Please verify your network settings and try again. 1 - 2 - 3 - Network connection established successfully, but official servers are unreachable."

If anyone has even the slightest experience with this ♥♥♥♥, PLEASE REACH OUT so ma homie can continue playing CS and ask russians if they like Borscht or Pelmeni.

I like Boršč with pineapple

Restart Everything:

Restart CS2.
Restart your PC.
Restart your router/modem.

Check Steam Status:

Valve servers might be down. Check Steam Status to see if matchmaking servers are offline.

Verify Firewall/Antivirus:

Make sure your firewall or antivirus isn’t blocking CS2 or Steam.
Add CS2 and Steam as exceptions in your firewall and antivirus settings.

Check Your Internet:

Test your internet connection with a speed test.
Switch to a wired connection if possible.
Restart your network adapter:
Press Win + R, type cmd, and press Enter.
Run: ipconfig /release → ipconfig /renew.

Verify Game Files:

Open Steam → Library → Right-click CS2 → Properties → Installed Files → Verify integrity of game files.

Disable VPN or Proxy:

If you’re using a VPN, turn it off. Some servers might block VPN traffic.
Update Network Drivers:

Check if your network drivers are up to date. Use Device Manager or a dedicated tool.
Change DNS:

Switch to Google’s DNS:
Primary: 8.8.8.8
Secondary: 8.8.4.4

Advanced Steps (if the issue persists):
Flush Your DNS:
Open Command Prompt as admin.
Type: ipconfig /flushdns → Press Enter.

If nothing works, try reinstalling CS2 or Steam entirely.

Restart pc ✓
Restart CS2 ✓ (if you mean close and re-open)
(We'll restart the router next)

All of his current servers are set to chinese for some reason, he lives in Europe
He even has a server on his list which appears offline when looking at the official servers

(I think we verified his firewall, not sure if we did it right so any tutorial you could point us to?)

Not sure if his firewall is blocking CS, and got no idea how to check that.
Add CS2 and Steam as exceptions in your firewall and antivirus settings ✓ (even added extra ports but did not help at all)

Test your internet connection with a speed test. ✓ (300Mbit download, 60Mbit upload)
Switch to a wired connection if possible. ✓

Restart your network adapter:
Press Win + R, type cmd, and press Enter.
Run: ipconfig /release → ipconfig /renew. Will try next.

Verify Game Files:

Open Steam → Library → Right-click CS2 → Properties → Installed Files → Verify integrity of game files. ✓ (found nothing)

Disable VPN or Proxy:

If you’re using a VPN, turn it off. Some servers might block VPN traffic.
Update Network Drivers: ✓ (he isn't using any)

Check if your network drivers are up to date. (will check it next, never has updating drivers resolved any of my issues but will still try)

Use Device Manager or a dedicated tool. (amd adrenaline software should do it)

Change DNS: ✓

Switch to Google’s DNS:
Primary: 8.8.8.8
Secondary: 8.8.4.4 ✓

Advanced Steps (if the issue persists):
Flush Your DNS: ✓
Open Command Prompt as admin. ✓
Type: ipconfig /flushdns → Press Enter. ✓
(we restarted his pc aswell just like the cmd told us to but it didn't resolve the problem)

Reinstall Steam or CS2:
If nothing works, try reinstalling CS2 ✓ or Steam entirely. (will try re-installing steam next but will do as the last step.)


I appreciate you for giving more info than most tutorials, I don't wanna take up some of your time but we're quite desperate, so if possible would you be able to reach out on discord? Some of the steps can be quite hard to try and google and I feel like it could ease things up a bit. My discord is "Shotgunnn", let me know when you've sent the request. No pressure dawg, already appreciate everything you've done.

[im wit the gng gng]

same problem done everything and reseted my pc

[skOsH♥]

Type all five of these in command prompt, one line at a time, in order.

ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh int ip reset
netsh winsock reset

Sometimes I unplug my modem for about a minute as well and let it do most of this automatically, as well as it purging stored up data.

I'll also delete the %temp% folder of everything that will delete, then "delete temp files" after clearing the shader cache.

And lastly reinstalling cs2.

^Doing all of this fixes the vast majority of my jitter. I have connection set to unrestricted and fps_max at 0/unlimited.

The cloudflare speedtest is very helpful, it will tell you your packet loss, upstream jitter, downstream jitter, etc.

I'm kinda late to this but have u found any solution to this, I've been facing this issue since forever and i know its because of my university's internet (I live in a dorm and its inside the campus)
