Can no longer fetch from Aure devops repo

[greay]

I'm familiar with the ssh-add -AK (now ssh-add -apple-load-keychain --apple-use-keychain), but as of recently that no longer works. I'm still able to pull & fetch from the commandline, but not from GitUp.

The error I get is:

Failed connecting to "origin" remote: failed to start SSH session: Unable to exchange encryption keys

which is reported in a now closed issue from 2018 (regarding GitHub).
