I can't join servers on my nintendo switch

Here is a thread that might actually help with your issue: I can't join minecraft servers on nintendo switch - Microsoft Community

Hey there diamondwolffx,

Thanks for reaching out to the Xbox Forums community for advice on accessing cross-platform play for Minecraft. I can totally understand how this situation could be confusing.

I suggest getting in touch with Mojang as they will be best equipped to handle issues with access cross-platform play through Minecraft.

Also, just to make sure I'm reading correctly, are you playing this off of a Switch?

If you are, it would be best to reach out to
Nintendo at some point for more accurate troubleshooting pertaining to that console.

If you are using an Xbox, I recommend going to Settings> Devices and Streaming> Blu-ray> persistent storage in the Xbox One Guide and clearing that three times. Once
that has been done, go to Settings> General> Network Settings> Advanced Settings> Alternate MAC address, clearing that and letting your console restart as a quick preliminary means of troubleshooting.

Hope this information is helpful.

Thanks for reading!

I'm having the same issue. On the Nintendo Switch I can not connect to any servers. On my Android phone, i can connect to servers.

did you find a solution to this problem because I havent yet

Great Question,

Check to see if you can sign into another account and if you can then see if you can sign out of your Microsoft Account and maybe Hard Reser your Switch by Fully shutting it down if that doesnt work go to https://support.xbox.com/contact-us/
For more detailed help

Thanks,
