SSH connection client_loop: send disconnect: Broken pipe
Asked by Mauro Ciancio:

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

```

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:

author: Ben
body: 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!

author: Mauro Ciancio
body: 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?


author: Ben
body: 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!
