### Summary Alibaba Cloud took a gitlab server, did not resolve the domain name, and bound the hosts `127.0.0.1 git.server`. Another machine had gitlab-runner to build the code, and the host on the machine also bound `116.*.*.17 git.server`, there is no problem with using ssh to clone code normally. ### Steps to reproduce When building with runner, the following error occurs: fatal: unable to access 'http://gitlab-ci-token:xxxxxxxxxxxxxxxxxxxx@git.server/tuitui/test-ci.git/': The requested URL returned error: 500 Grant root user ：gitlab-runner install --user=root --working-directory=/var/www ### I don't know how to solve this problem now. thx!
