I installed git and gerrit and jenkins on the same PC and both gerrit and git works fine.

Environment:

windows 10.0.17134 N/A Build 17134
Jenkins 2.204.3
git version 2.24.1.windows.2
Gerrit 3.1.2

I signed up a new user account which named "jenkins" on gerrit server and added it into non-interactive group . but when I started a new project on jenkins I enconunterred an iusses like below:

when I try to use http url of git repository ,it always shows like below.I'm sure of using the correct http credential generated for gerrit user and test it for many times .

I use the same http credential on gerrit trigger ,it works fine.

and when I use these commands to test it manually it works fine too.
