[2023] Problems connecting to multiplayer

We have three possible workarounds that may solve it:

Disable IPv6
- Close CK3
- Go to Control Panel > View Network status and tasks > Change adapter settings (left side)
- Find your Hamachi Connection and Disable it
- Find your Internet connection adapter (for me, it was WiFi)
- Right click your internet adapter and select properties
- Scroll down to find "Internet Protocol Version 6 (TCP/IPv6) and uncheck the box
- Select Ok
- Start up CK3 and should work.

Disable all other network adapters
Go to Windows Control panel.
Click on Network & Internet.
Click on View Network Status.
Quick Tip: You can also quickly access these settings by right-clicking the network icon in the taskbar and selecting the Network & Internet settings option.
Click on Change adapter options.
Right-click all network adapters that are not connected to the internet and select the Disable option.


Use a VPN
- Obtain a VPN
- Set the country to the US (why this works is also an enigma ><)
- Start the game
- Sign in and see if it "sticks"


Good luck!  

FrostDragonII said: When I disabled the IPv6 protocol, my internet shut off immediately. I don't know why this is but that definitely didn't help.

I've recommended that change to dozens of people before and never had that happen, I have frankly no idea why it had that effect on you. It might be worth drilling down on that with any Windows or ISP support you might have access to.  

A thought occurred - IPv4 was enabled in that menu, yeah?
