SSH connection client_loop: send disconnect: Broken pipe

Hi, I'm having intermittent errors when pulling from bitbucket.

It fails with

client_loop: send disconnect: Broken pipe

 

It's kind of random, sometimes it works, sometimes it doesnt.

 

This is the ouput when running

ssh -Tvvvv git@bitbucket.org

G'day Mauro!

Based on the output you have provided, this appears to be a local network issue - where the connection is intermittently dropping out when attempting to connect to Bitbucket.

Please run and provide the following output from these commands (you may redact sensitive info):

tracert bitbucket.org (or traceroute bitbucket.org)
nslookup bitbucket.org (or dig bitbucket.org)
ping bitbucket.org

We have further local network troubleshooting instructions here also:

Hey Mauro,

Thank you for providing the output.

I am unable to reproduce this issue on my end, therefore it appears that this may be a local network issue.
Are you able to try to perform SSH operations on a different network and monitor to see if you receive the same result?

Cheers!

- Ben (Bitbucket Cloud Support)

That's right, it only fails in a specific network (digital ocean). From different networks it works great.

I wasnt sure to raise a ticket with digitalocean, but it's seems its their issue, right?

Any hint in how to raise an issue with them?

Ben Atlassian Team Apr 28, 2022

Hi Mauro,

If the connectivity is fine when using other networks - I believe that this is a fairly safe assumption.  
I am not too familiar with DigitalOcean to be honest, however I have found a support contact page that may be of assistance to you:
https://www.digitalocean.com/products/support

Cheers!
