What's needed for HTTP->HTTPS redirect in load balancer?

Posted on October 2, 2019
Load Balancing
Asked by fredrikbostrom

I’m using a couple of load balancers in front of my droplets and I only want to allow HTTPS traffic to the LB. There’s an option in the load balancer to “Redirect HTTP to HTTPS” that supposedly should redirect all calls on the 80 port on the load balancer to port 443?

This doesn’t seem to work as I get a “connection refused on port 80” when I access the droplet through the loadbalancer over http.

Is there some additional configuration needed for this redirect to work?

Hello,

Yes, it is possible to force the HTTP to HTTPS redirect. You can follow the steps on how to do that here:

Hope that this helps! Regards, Bobby

Thanks @bobbyiliev, that’s what I’ve done but when I test it out with curl http://domain.com I get a connection refused error for port 80. Using https works as expected.

I have configured a firewall blocking public access to port 80 the droplets from the internet, but I suppose that shouldn’t affect the redirecting, which should happen in the load balancer.

I must be doing something wrong, but can’t see what that would be.
