How To Fix: Could Not Connect To Steam Network

You are unable to connect to Steam Network, so you cannot play on VAC secure servers. Please check your network connection and try again. If the problem persists, verify that your Internet security software isn’t blocking Steam connections.

Client Initialization Failed

Your client was unable to connect an initialization of Steam Network. Please try restarting your computer and trying again. If the problem persists, verify that your Internet security software isn’t blocking Steam connections.

These two errors were preventing me from playing multiplayer TF2, both casual and competitive. I found this VAC error especially odd because I had been able to play since last December without issue. Being unable to initialize my Internet connection, I turned to Google where I was lucky enough to find a Reddit thread mentioning the same problem. Turns out, there’s an easy fix:

Open up your command line (cmd) and execute these commands:

netsh winsock reset catalog netsh int ipv4 reset reset.log exit steam://flushconfig 1 2 3 netsh winsock reset catalog netsh int ipv4 reset reset . log exit steam : / / flushconfig

If the second command fails, try changing “reset.log” to “reset.log_ %COMPUTERNAME%” and then put in your computer’s name instead of the “%”. If it still doesn’t work, you can leave it as “reset.log” without the “%”.

After these are successfully executed, close your command line and restart Steam. You should now be able to fully initialize your network correctly.

I hope that this helped out anyone else having the same problem. If there’s anything I missed, please let me know! Thank you for reading.
