[2020] Multiplayer connection issues

Hello Faulty-Brain,

In order to better help you after you have tried our troubleshooting with no success, could you please list here in the form of bullet points what kind of issues you have been having in the game, then we will be able to investigate each one and report them to the dev team after gathering enough information.

Thank you for your help with this.

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 path 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"  

If your issue is caused by the game/launcher/nakama, The situation has continuously improved, in the sense that fewer and fewer users are affected.

However it is possible to get similar symptoms from external causes like firewalls, slow internet connections and so on.
