GIT ERROR: fatal: unable to access 'https://dev.azure.com/****/': Recv failure: Connection was reset while cloning

Question

Cloning a repository, pushing , fetching and pulling code with git from Azure Devops via VSCODE, GITExtensions, GIT BASH results in a 'fatal unable to access' & 'CONNECTION WAS RESET' ERROR around 80% of the times. Sometimes it works and while spamming the 'git push' command it works 1 out of 20 times but it's random.

I need help in resolving this 'Connection Was Reset' since i'm unable to work for my client.

For more info, please refer to: https://github.com/git-ecosystem/git-credential-manager/issues/1150 I already explained the information here aswell

Screenshots: Git Clone via CMD VSCODE Issue

I think the problem might be related to internet issues but then again cloning from another computer on the same network works as expected.

Things i've tried:

• Resetting my password - Unsuccesfull
• Removing the GIT Credentials in Windows Credential Manager - This allows me to re-enter my password (which is the same as the one used to log into the azure devops) and to SUCCESFULLY CLONE / PUSH only once, afterwards it fails again.
• Re-install GIT and don't install GIT Credential manager
• Just spamming the 'push' and 'sync changes' buttong in vscode makes it work 1 out of 30 times miraculously.
• Sometimes if i remove my GIT credentials on my local device, i am prompted to add a password again (VSCODE & GIT both prompt me), after providing my password and my 2-Factor Authenticator , i get a 'unable to access' issue and a fatal error.
• Flushing DNS
• Cloning from another computer (WORKS FINE) ** Please note that for 1,5 weeks, there was no issue in pushing and cloning repo's with my clients email address they provided me with, also surfing to the browser and editing code on devops itself (still) works fine. all of a sudden one day after arriving at home, this error occured.**

Answer 1

My case was McAfee VPN. Disabling it solved the problem. I'm using Windows 11 on ASUS Core Ultra 9 285H laptop.

Answer 2

Similar to the Killer utility, I had to disable the Intel utility. It's called Intel Connectivity Network Service and I found it opening services.msc. Stopping the service will fix it temporarily, and disabling the service prevents it from restarting after a reboot

Answer 3

my issue is with IP6. i disabled IPV6 on my router and i can clone without any issue

Answer 4

It could just be a matter of the network connectivity of your internet provider.

For example, I had a similar error when I connected my laptop via a hotspot connection established on my mobile phone. The problem disappeared when I switched the data transfer on my phone to another cellular operator.

Answer 5

I tried doing git push a couple of times on my home wifi, it didn't work. Then I tried using my phone's hotspot and after 3-4 attempts it worked. Although, I recommend using SSH

Answer 6

Answered in the comment from @chrisb; I've added here to make it more obvious:

FWIW I had this issue on a brand new Dell XPS system with Windows 11 pro on both wireless and wired connections. I also verified a simple 'curl example.com' failed about 30% of the time. with 'curl: (35) Recv failure: Connection was reset' and I was often seeing ERR_CONNECTION_RESET in a browser. For me Dell had preinstalled some sort of helper app for the 'Killer' network card and as soon as I opened this and turned off "Killer Prioritisation Engine" the problem went away. So if you have anything like this might be worth a try.

Answer 7

I had this problem and the solution was to turn off IPv6 in my Internet adapter settings

Solution from https://elguerre.com/2023/06/12/unable-to-access-dev-azure-com-git-repo-via-https-recv-failure-connection-was-reset/

Answer 8

The one work I do not see in your question or issue is token.

HTTPS URL to Azure (or GitHub) are supposed to use as password a PAT (Personal Access Token)

For Azure access: "Use personal access tokens".

Assuming C:\Program Files\Git\usr\bin and C:\Program Files\Git\mingw64\bin are in your %PATH%:

• check your credential helper: it should be "manager" (or manager-core):

  git config --global credential.helper
  

• Check if you have any credentials already cached (from a simple CMD):

  printf "host= dev.azure.com\nprotocol=https\nusername=YOU" | git credential-manager get
  

  Replace "YOU" by your Azure login account name

• if what you see is empty or is not your token, register it:

  printf "host= dev.azure.com\nprotocol=https\nusername=YOU" | git credential-manager store YOUR_TOKEN
  

Then try again your HTTPS access (push/pull/fetch)

Note: this is followed with git-ecosystem/git-credential-manager issue 1150, which includes:

For anyone who want to get rid from this annoying issue, need to disable IPv6.

Answer 9

I had the exact same problem. At some point it stopped working completely.

So I ended up cloning my repo with SSH. To do this select you need to configure your SSH key. In the Clone Repository Select SSH and then Manage SSH Keys.

Check this link to get some help at creating your SSH key.

https://learn.microsoft.com/en-us/azure/devops/repos/git/use-ssh-keys-to-authenticate?view=azure-devops

It says that you use ssh-keygen to generate your key. I can run that command in the command prompt. I don´t know if everyone can, or I just installed something previously. Anyway, you can generate that key with other tools, like PuttyGen.

When you finish, just clone your repo with the git@ssh.dev.azure.com:v3/organization/project/repo that you can copy from the Clone Repository screen.

Notes:

• Before changing to ssh, my workaround was to connect to a VPN (work vpn or kaspersky vpn). This worked for some months.
• Upgrading to Windows 11 didn't work, no need to try.
• I haven't installed a fresh copy of windows. So I don't know if this will work.

(Edited)

• I uninstalled my antivirus, and disabled windows firewall. Still not working. But the VPN workaround worked again, even after reinstalling it. Still using ssh.
