Pair to mac error Failed to execute 'grep "ssh-rsa ...."-CodePudding

I am trying to pair my Macbook with Visual Studio 2022 but after entering the credentials I received the following error in the gui dialog: "An error occurred while trying to establish an SSH connection with SSH keys to '192.168.178.27:22'"

When checking the logs there is the following error:

The exception about the missing file is misleading. First of it does not exist but if you watch the folder during the connection process it gets created among with other files and when it fails it gets deleted again. So I am assuming that is a different error.

And ssh login to the machine and everything works fine. I can ssh into it and if you enable verbose login there are other commands as well as scp which are being executed just fine.

Has anyone encountered this problem and has a solution?

Visual Studio 2022

OSX Ventura with XCode 14.0.1 and Visual Studio 17.3.8 (build5)

CodePudding user response：

You can check that your firewall allows incoming connections through port 22 (the default for SSH), and check that the IP address you are using for the Mac is correct, you can find the IP address under System Preferences > Sharing > Remote Login on the Mac. Then you can check whether the SSH server can be connected normally, you can refer to the steps in the official Xamarin.iOS documentation.

Did anyone get a resolution to this? seem to of started when I updated the mac to MacOS 13
