[2021] I can't play multiplayer in CK3

We are aware of an issue where some customers can't login/stay signed in with their Paradox account which then results in being unable to play multiplayer. With the latest patch it solved it for a vast majority of players but sadly not everyone >
Rest assured we're investigating this further and both the CKIII and tech team are trying to figure out the cause (and a solution!) but sadly there isn't a confirmed workaround for the time being . 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

1. Go to Windows Control panel.
2. Click on Network & Internet.
3. 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.
4. Click on Change adapter options.
5. 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"  

The process I posted above is exactly meant to address that issue, but you don't mention it. Please go through it.
