[keycloak-user] clients behind load balancer issues

All local environment 1 keycloak 1.7 & 1.9 listening on port 8080 2 tomcat 7 with java webapp using Keycloak filter (not the adapter) 1 nginx load balancing the 2 tomcats. Nginx config below upstream jeremy { server localhost:8082; server localhost:8999; } server { listen 80; server_name localhost; location / { proxy_pass http://jeremy/; proxy_redirect off; proxy_set_header Host $host; } } My Keycloak client all defaults, 1 only valid redirect_uri. As soon as I validate the login in keycloak it gets crazy with ERR_TOO_MANY_REDIRECTS The same thing happen in AWS having a ELB > tomcats or ELB > NGINX > tomcats. Anyone had a similar issue ?
