If you cannot reach repositories over ssh, but https works fine, consider looking into the following.
First, make sure you can access Gitea via SSH.
ssh git@myremote.example
If the connection is successful, you should receive an error message like the following:
Hi there, You've successfully authenticated, but Gitea does not provide shell access.
If this is unexpected, please log in with password and setup Gitea under another user.
If you do not get the above message but still connect, it means your SSH key is not being managed by Gitea. This means hooks won’t run, among other potential problems.
If you cannot connect at all, your SSH key may not be configured correctly locally. This is specific to SSH and not Gitea, so will not be covered here.
