GCM slow to get credentials over VPN

[AsWaM]

Hello!

I was using GCM 1.18.0, and updated to 1.20.0 just to see if it solves the issue. It doesn't.

I set the following flags: GCM_TRACE=1
GIT_TRACE=1

Log GCM 1.18.0 (22 seconds)

18:19:22.874055 run-command.c:637       trace: run_command: 'git credential-manager get'
18:19:44.203789 exec-cmd.c:236          trace: resolved executable dir: C:/Users/samal/AppData/Local/Programs/Git/mingw64/libexec/git-core

Logs GCM 1.20.0 (21seconds)

18:42:58.320135 run-command.c:640       trace: run_command: 'git credential-manager get'
18:43:19.646125 git.c:576               trace: exec: git-credential-manager get

Sometimes it is instant, sometimes it takes 20 seconds...

Only happens when a VPN is active, otherwise no problem in the company network

I can corroborate this. I am having the same problem, with Windows 10 and OpenVPN.

@AsWaM This was resolved for me by upgrading the OpenVPN client I was using.
