我有一个通过omnibus安装的本地Gitlab服务器，我们称其为gitlab.own.com，还有一个gitlab-runner docker映像，我想在其中运行ci，它们都在同一台机器上。我已经成功注册了跑步者，但是每次ci运行时都会出现此错误：

Running with gitlab-runner 11.10.1 (1f513601) on runner11 mQZzHdu8 
Using Docker executor with image php:7.0-cli-jessie ...

fatal: unable to access 'http://gitlab-ci-token:xxxxxxxxxxxxxxxxxxxx@gitlab.own.com:1234/path/to.git/': Recv failure: Connection reset by peer
ERROR: Job failed: exit code 1

任何想法可能是什么问题？
