Sometimes when using an external load balancer to handle HTTPS Redirects and HSTS, there can be an issue where CentreStack is also forcing HTTPS and the load balancer has already terminated the SSL and is forwarding plaintext HTTP. This effectively creates an infinite loop of trying to force the traffic back to HTTPS. The web browser will detect this and ultimately stop trying to make the connection, resulting in the "ERR_TOO_MANY_REDIRECTS" error.
- If your load balancer supports the "Re-Encrypt" function, you can enable this. It will ultimately decrypt & terminate SSL at the load balancer, start it again, which shall be considered a "SSL-de-acceleration", but it will keep the HTTPS instead of converting it down to HTTP.
- If you would prefer to use your load balancer to terminate the SSL and then forward plaintext HTTP to your CentreStack server, you will need to login as the Cluster Admin, select Cluster Control Panel, select Worker Nodes, then click the small gear in the top left corner, and unselect the settings for "Always force SSL on Login" and "Always force SSL for Native Clients".
