[mfojtak]

this bug has been removed in beta.6 but appeared again in gcr.io/google_containers/nginx-ingress-controller:0.9.0-beta.6
It makes the nginx ingress controller useless

[gianrubio]

@aledbf I got the same issue as @mfojtak described. Does #862 fix this issue?

[aledbf]

@gianrubio yes. That is not included in beta 8. Please use quay.io/aledbf/nginx-ingress-controller:0.146
