Suddenly he can’t click on the hero: “failed to agree on a key exchange method”

Question

"git push heroku" suddenly fails. (I installed Node.js, and I think it might have updated some things and somehow broken.)

I read all related posts; this does not tell me what kind of exchange was “offered”, and everything looks as if it matches, but the challenge fails, and I am at a loss.
I made heroku auth: login successfully.

ssh [e-mail] -v gives me the following:

Answer 1

This morning I ran into the same problem.

I can avoid this problem by changing the git of the remote url as shown below.

from: git @ heroku.com: app-name.git

: https://git.heroku.com/app-name.git

git remote rm heroku git remote add heroku https://git.heroku.com/app-name.git
