Bitbucket port 22 connection timed out

[Roman Zahradník]

Hello I am trying to connect to `ssh -Tvvv git@bitbucket.org` 

But I am getting:
OpenSSH_8.2p1 Ubuntu-4, OpenSSL 1.1.1f 31 Mar 2020
debug1: Reading configuration data /home/romzah/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: include /etc/ssh/ssh_config.d/*.conf matched no files
debug1: /etc/ssh/ssh_config line 21: Applying options for *
debug2: resolving "bitbucket.org" port 22
debug2: ssh_connect_direct
debug1: Connecting to bitbucket.org [2406:da00:ff00::34cc:ea4a] port 22.


Can somebody help me? I went through all of the similar problems over the internet and here in forum but nothing helped me so far.

Hi Roman

welcome to the Atlassian community.

How are you connected to the internet is there somewhere a proxy inbetween.

Any chance that firewall rules are in place that block access to bitbucket.org

Cheers

Kurt

I am not aware of that, the weird thing is that it was working last week ago without any problems. For example I was checking GitHub and the command work seamlessly.

So I was experimenting a little bit more and if I leave it hanging for 30 minutes to 1 hour it download the content eventually but still I would like to find a solution however I am not sure if the problem is on your side or with my ISP or on my machine

The script first checks a list of IPv6 addresses and all of them time out but after it tries IPv4 it works here is the output of script that run successfully:

Ok I have added line to etc hosts file according to the aforementioned output: 


18.205.93.2 bitbucket.org

However can you still please explain why would not IPv6 addresses not work?

[Jan Podmajersky]

Thank you @Roman Zahradník  I experienced the same issues.

All of sudden ssh to bitbucket stopped working. Adding ip address to `/etc/hosts` helped. I am on ubuntu 18.04 and not using any proxy/vpn.

I would be greatful if we could hear some explanation from atlassian, so we can prevent it in the future.

Thank you

Same issue here :

script for fix on windows (needs to run in cmd with admin-rights)

echo adding bitbucket to hosts file in Windows 10
cd C:\Windows\System32\drivers\etc\
echo 18.205.93.2 bitbucket.org>> hosts

[fagianijunior]

Same error here, I am using Arch Linux.
I would like to know why this happens? until 09/05/2020 it worked perfectly.

has my provider added some type of block?

Adding 18.205.93.2 bitbucket.org on /etc/hosts fix this error.

[Kurt Klinner]

@fagianijunior Can you check https://confluence.atlassian.com/bbkb/recent-ipv6-changes-840796883.html to see if that fits to your problem?

[fagianijunior]

I do this workaround, and it works. But, I am not behind a firewall blocking IPV6 traffic.
But, is working.
