this error indicates you are being served an HTTP webpage instead of a JSON API endpoint. The most common root causes for this error is that you configure an http address instead of https, and gitlab automatically tried to redirect. We have also seen people encounter issues with reverse proxies (nginx, etc) in which case you should check your configuration.

Example:

So this issue is not caused by gitlab version? Someone upgrade the gitlab version to 11.x and fixed this.  
Using [https://gitlab.xxx.com](https://gitlab.xxx.com) can fixed this?

The redirect URI included is not valid.

My gitlab https server is fine.

This is my drone config:

```auto
docker run \
  --volume=/var/lib/drone:/data \
  --env=DRONE_GITLAB_SERVER=https://gitlab.xxxx.com/ \
  --env=DRONE_GITLAB_CLIENT_ID=3daf03e17fcb31e29ba22edfe2743c06c9267c41b7ddbfecd38888eb2952a660 \
