Can't Share Screen after Big Sur 11.2 Update

I share my M1 MacMini screen on my 2018 MacBookPro but since doing the 11.2 update on both machines, I can't share the MacMini screen on the MacBook. I get the error "Unable to communicate with “ChuckMacMini”. Make sure the remote computer is available and the firewall is not blocking screen sharing."

I can connect to the MacMini and can see all the drives but not share the screen after the update.

I can share the MacBook screen on the MacMini. Both machines have Screen Sharing On and access is allowed for all users on both machines.

Mac mini, macOS 11.2

Hello CPW,

Its sounds like you are not able to share your Mac mini screen with your MacBook Pro. We understand how important this is to you and we are here to help.

Let's review all of the steps outlined here: Share the screen of another Mac

If the issue persists, can you provide a few more details? Which macOS version do you currently have on your MacBook Pro? Does the issue persist in Safe Mode: Start up your Mac in safe mode Also, are you able to share your screen with any other Macs

Cheers!

Hello,

I have the very same problem. I used to connect my personal MacBook Pro to shared screen of my mother MacBook. It worked very fine since she upgrade to macOs 11.2. Since, I get the same message : 'Unable to communicate with [ip]. Make sure the remote computer is available and the firewall is not blocking screen sharing.'

Something has obviously changed. All the router setup, port redirection, remains unchanged and redirect perfectly the port 5900. I can't event reach anymore the login form.

Thanks in advance for your real help.
