git LFS
Asked by Kurt Duyck:

As soon as I want to push LFS files , even as soon as adding a .gitattributes file defining git LFS I get a "Connection to bitbucket.org closed by remote host."   

Is this a license issue? A network issue? How to troubleshoot this?

Kind regards  
Kurt

body: Hi Caroline

Thanks for your help.   
I am using SSH on windows terminal (powershell), so I needed some time to figure out how to set the environment vars. (On windows it is line by line, $Env:GIT_TRACE=1)   

This gave me some nice insight on the inner workings of the connection. I saw some retry's and had to add my passphrase at some point. However this time the command got executed and the .gitattributes file was pushed to Bitbucket.   

What follows is the verbose output I got: (minus some sensitive data)   
Thanks for looking into it, any recommendation is highly appreciated.   

One line in particular caught my attention:   
*Remote "origin" does not support the LFS locking API. Consider disabling it with:*

Also I am using IPv6.

Kind regards  
Kurt

body: Hi, [@Kurt Duyck](/t5/user/viewprofilepage/user-id/130014), thank you for reaching out to Atlassian Community.

It seems to be a network issue, so in order to further investigate what is causing this, could you please share the following information with us?

* Is this problem happening using both HTTPS and SSH?

* Is this issue affecting other repositories? In case this is happening to this specific repo, could you share the last 3 letters of the workspace and repository name so we can identify this in our system?

* Could you please run the following commands and share the output with us? **Please remember to remove any private/sensitive information.**

  * This will show us the verbose of the command, so we'll be able to see where exactly this command is failing:

    * If you are using SSH:

          GIT_TRACE=1 GIT_SSH_COMMAND="ssh -v" GIT_CURL_VERBOSE=1 time <git command>

    * If you are using HTTPS:

          GIT_TRACE_PACKET=1 GIT_TRACE=1 GIT_CURL_VERBOSE=1 <git command>

* Are you using IPV6 or IPV4?

  * [`https://test-ipv6.com/`](https://test-ipv6.com/)

* If you have access to another network (e.g. a 4G network), could you please try to make this specific push using that other network?

Thank you.

Kind regards,  
Caroline

Yesterday I managed to push the .atrributes to bitbucket. However today when I tried to push a first LF (a fig file, which is a figma source file) I encountered this error:
