I can't join the minecraft nether beta

I have found a solution. After I deleted my original insider account I created a new one and joined the rtx minecraft beta other than the nether beta which was what I was in. I then updated minecraft to rtx and unenrolled and reverted back to the normal
minecraft version.

Hi !

If you have a Beta version of Minecraft, I think you can only join people with the same beta version. Maybe your others friends can't be joined because they don't participate to the beta program.

I am having same issue, my friend has xbox one 1.16 nether update version and i have the nintendo switch 1.14.3 version and it will not let me into realm. The realm acct/world was created on my friend’s xbox one. Is there any solution to this problem?

As the others have said previously, your friend on Xbox is in the Minecraft Beta. The only way you would be able to join their realm is if they left the beta and downgraded to the "current" version. Good Luck!

According to what's mentioned in the link below (section: Essential information before participating in a Minecraft Beta), you can't switch back and forth between the two programs. You can find more information about this in the following link :

Is it possible that one of you or your friends has joined the Minecraft Beta Insider program?

If so, you probably have different versions of the game, and only players with the same Minecraft version can join each other's worlds.

Check that you all have either the official Minecraft version of 1.11.4. If one (or more) have the current Beta version of 1.13.something, then you can't join each other's worlds.
