Re: [keycloak-user] Keycloak invalid redirect_uri with port 0?

Hi, I’ve tried a couple things in that comment so far: 1) Verified I’m sending through the headers and the spring boot app is receiving the headers: Oct 05 05:15:27 server01.edgewoodsoftware.com java[25117]: 2018-10-05 05:15:27.576 INFO 25117 --- [nio-8042-exec-2] a.c.u.server.controller.IndexController : host=www.example.com Oct 05 05:15:27 server01.edgewoodsoftware.com java[25117]: x-real-ip=1.2.3.4 Oct 05 05:15:27 server01.edgewoodsoftware.com java[25117]: x-forwarded-for=1.2.3.4 Oct 05 05:15:27 server01.edgewoodsoftware.com java[25117]: x-forwarded-proto=https Oct 05 05:15:27 server01.edgewoodsoftware.com java[25117]: x-forwarded-host=www.example.com Oct 05 05:15:27 server01.edgewoodsoftware.com java[25117]: x-forwarded-port=443 I tried setting the spring boot keycloak config setting: keycloak.ssl-required = none That did remove the port 0 in the redirect_uri being generated but it also set the redirect uri to be http instead of https, which seems like it’d be bad. I do have nginx set to redirect all http requests to https anyway. Is there something else I need to do to get the spring boot app to generate the correct redirect_uri with https? There must be like some magic config setting I’ve missed somewhere. I’ll keep digging and share what I find.
