mrahb (mrahb) asked a question.
While using sft ssh command to ssh in my instance i am getting error related to unknown port 65535.
I tried below mentioned command while I was troubleshooting the issue.
Unable to negotiate with UNKNOWN port 65535: no matching host key type found. Their offer: ssh-rsa
Can someone please provide possible solutions ?

Hello @mrahb (mrahb),
I was checking your error message and it looks like the problem can be the ssh-rsa negotiation. This release disables RSA signatures using the SHA-1 hash algorithm by default.
This can be confirmed in the link below: https://www.openssh.com/txt/release-8.8
