Git credential manager automatically erases windows credentials

Open meenalmenghani opened this issue 6 years ago • 2 comments

Hi

Issue: I am using proxy to connect to GitHub(proxy is added in .gitconfig), on git fetch(or any command) first time GCM prompts for credentials and stores it in windows credential for both GitHub and proxy. It works fine for some time but after about an hour again on git fetch (or any command) GCM automatically erases the proxy credentials from Windows credential and prompt again for credentials.

First time GCM stores credentials logs GIT 2.22.0 and GCM 1.19.0:

Same issue with GCM 1.18.3

But is working correctly with GCM 1.17.2

Could you please help in resolving the issue.

Thanks.

Any Update?

meenalmenghani avatar Jul 08 '19 06:07 meenalmenghani

@meenalmenghani

The erase command is being called from git because an authentication failed. It would be very helpful to see the request that led to the failure to help diagnose the issue.

Can you please try with GIT_TRACE_CURL=1? Let us know what error leads to the failure.

As always please redact any personal information from logs before posting.
