Rancher 2.3.1 ERR_SSL_PROTOCOL_ERROR

I’m hopping someone has an idea how to solve the problem because I can’t find a solution.

i have created a workload, containing a application that run on port 80. Afterwards I have added under Load Balancer an Ingress with Port 80 and Annotations

nginx.ingress.kubernetes.io/force-ssl-redirect. "false

The Problem:
The domain is always redirected from http to https and I get the error in the browser: ERR_SSL_PROTOCOL_ERROR

How can i disable the http to https redirect and use Port 80 on the Ingress?

regards
dm
