OpenSSH_9.0p1 cannot connect to repository

angelodicrescenzo

I've installed the OpenSSH 9.0p1 on my MacOS Monterey (12.5.1) via brew but I can't connect to my bitbucket repositories. I haven't any issues with OpenSSH_8.6p1 that is installed in the OS.

Does anyone have this issue and knows how to solve it?

Any help will be appreciated.

These are the log when I try to connect:

Hi @angelodicrescenzo,

I have installed OpenSSH 9.0p1 on a MacOS Monterey (12.5.1) and I see no issues connecting when I run ssh -vvv git@bitbucket.org or when I clone/push to Bitbucket repos via SSH.

The "Operation timed out" error usually indicates a network issue. Do you get this error consistently when you run this command?

Is your computer behind a corporate firewall?

Can you connect from your Mac to a different network (e.g. a 4G network) and check what output you get from ssh -vvv git@bitbucket.org then?

Kind regards,
Theodora

Hi @Theodora Boudale

I can exclude connection issues because when I use the ssh client that is installed natively on the Operative System (OpenSSH_8.6p1) it works like a charm.

I'm not behind any firweall and I get the connection error consistently.

I'll trying with a cellular network as you suggest but I don't expect it will work for the reason I mentioned above.

Many thanks for your support.

Kind regards,

Angelo.

Hi Angelo,

Please let me know how it goes when you have the chance to test this with the same Mac, OpenSSH 9.0p1, and a different network. When you do, please let me know the outcome and what IP bitbucket.org is resolving to in the output (e.g. on the output you shared with your current network it is resolving to 104.192.141.1)

A second thing I would suggest testing is using the same Mac and also the same network, adding temporarily in your /etc/hosts file the entry

18.205.93.0 bitbucket.org

and then running the command ssh -vvv git@bitbucket.org again, and let me know what output you get. This is to narrow down whether the issue may have to do with Anycast Shift, detailed here:

You mentioned

Is this with the same Mac and before you installed OpenSSH 9.0p1 a week ago? Or are you using a different Mac with OpenSSH_8.6p1 now?

Kind regards,
Theodora
