Integrate gitlab ce 11.8.0 gives The redirect URI included is not valid

gitlab ce 11.8.0
drone 1.0.0-rc6 and drone 1.0.0

callbackUrl to gitlab application:

docker run
–env=DRONE_SERVER_HOST=ssdev dot 100tall dot com

when I type ssdev dot 100tall dot com, redirect to git dot xxxx dot com, show error:
An error has occurred
The redirect URI included is not valid.

*When I change gitlab to github, do exactly same steps, github success. *
Does gitlab must use https ?
thanks to read

Sorry for I can only post two links, use dot .

So how you resolve this problem?
