Mine has updated to version 1.21.100.
My PC is on this version, and so is my phone.
When you download the server from the official website, it comes at 1.21.100.7.
So, when I log in from my phone, it works, but when I log in from my PC, it says the version is incompatible.

same issue when installing brand new linux based bedrock server.
seems like up to date server is running on 1.21.100.7 whilst all other up to date clients are running on 1.21.100
Steps to Reproduce:
1, download Minecraft Dedicated Server Software for Ubuntu (Linux)
2, set up using default settings including port forwarding so its accessable via wan
3, try connect to server and encounter version issue
Observed Results:
when connecting to server other WAN get a unsupported version error. however when connecting via lan i have no issues
Expected Results:
Connect with no issues

This was the information from my Survival server:

This is after I updated survival today:

Still no change.
I spun up a new server without anything from the old one to see if the Switch would connect.
Version: 1.21.102.1
Build ID: 36160546
Branch: r/21_u10
Commit ID: 468d0e14b95e8c003f79d1a82cdaa729522efab6
Same error message.
I tried to change the port, with no effect on the Switch being able to connect.
This is still an issue.
Followed same steps as you Megan. I tried to connect to server via wan and lan and still not working.
I found something out. When you enter wrong IP or port, this message also pops up even though it doesn’t exist at all. Like it pops up instead of “Server not found”. But I found no solution for that. Maybe that can slightly help
Here I attached a video that shows joining to a completely made up IP and port. It say the same instead of “Server not found”. Normally (when the IP and port exists) it just joins me to the server without this message. So it’s problem in searching for the server or just wrong IP or port
