we have (once again) severe issues with some Bitbucket server, which basically toggles between these states:
ssh://firstname.lastname@example.org/dresearchfe/drdiagshell.git failed with exit code 128, output: email@example.com: Permission denied (publickey). fatal: Could not read from remote repository.
ssh://firstname.lastname@example.org/dresearchfe/drsbbs.git failed with exit code 128, output: ssh_exchange_identification: Connection closed by remote host fatal: Could not read from remote repository.
And rarely it simply works.
Can you please check, why the server refuses the connection.
As we had these issues already often before, I assume the basic problem should be already known.
