How to add a git remote using ssh with "-oHostKeyAlgorithms=+ssh-dss" needed?

[LMD]

Hi Everyone. I am having an issue adding a git remote to push to my production server that is hosted with GoDaddy. 

For example I use to be able to add it like this at it worked fine:

git add remote beta ssh://username@mysite.com/~/gitrepos/myrepo.git

When trying to push the beta I now get this error:

Unable to negotiate with "ip of server" port 22: no matching host key type found. Their offer: ssh-rsa,ssh-rsa-cert-v01@openssh.com,ssh-dss
fatal: Could not read from remote repository.

I then thought it was the ssh key so I created a new one. Imported the public key to GoDaddy and tested a connection in the terminal:

ssh username@mysite.com

And got the same error as above "Unable to negotiate..."

I then found out I had to use the following ssh flag "-oHostKeyAlgorithms=+ssh-dss" in order to connect successfully:

ssh -oHostKeyAlgorithms=+ssh-dss username@mysite.com

So my question is... How do I add this new ssh flag "-oHostKeyAlgorithms=+ssh-dss" to the git remote?

I figure out my issue. I had to add the following in my .ssh/config file:

PubkeyAcceptedAlgorithms +ssh-rsa
HostkeyAlgorithms +ssh-rsa
