git pull error: RPC failed; result=52, HTTP code = 0

[Shahrul Azim]

I encounter this error message when try to perform git pull on my linux server

[user1@test projectfolder]$ git pull -v
Password for 'https://usergit@bitbucket.org': 
POST git-upload-pack (949 bytes)
POST git-upload-pack (999 bytes)
error: RPC failed; result=52, HTTP code = 0

so far i have tried

1. increase postBuffer to 1048576000

2. using SSH 

in config

[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
compression = 0
packedGitLimit = 1g
packedGitWindowSize = 1g
[pack]
packSizeLimit = 1g
deltaCacheSize = 1g
windowMemory = 1g
[http]
pullbuffer = 50k
postBuffer = 1048576000

But still getting the same error. what else should i try?

Hello @Shahrul Azim and welcome to the Community!

Could you confirm if the same error happens when you do a fresh clone of the repository in a different folder? 

For that, you can use the command below that includes verbose logs and then share the output with us : 

GIT_TRACE_PACKET=1 GIT_TRACE=1 GIT_CURL_VERBOSE=1 git clone https://{username}:{app_password}@bitbucket.org/{workspace}/{repository}.git

Please note that the log output will contain an Authorization section with your encoded app password. Make sure to remove this information, and any other sensitive information, before sharing the logs here, as this is a public forum.

Thank you, @Shahrul Azim !

Hello @Shahrul Azim ,

Thank you for sharing the results. This seems to be an HTTP-related issue. I found this thread in stackoverflow from a user who was able to fix the issue by changing the compression of git : 

• https://stackoverflow.com/a/40917965

You may want to try those settings to see if it works for you.

Also, have you tried to clone over SSH? Does the same error happen? The following SSH clone command will bring verbose logs : 

GIT_TRACE_PACKET=1 GIT_TRACE=1 GIT_SSH_COMMAND="ssh -vvv" git clone git@bitbucket.org:<workspace>/<repository>.git

Thank you, @Shahrul Azim !
