Question

503 on load balancer through HTTPS. HTTP works fine.

I have an HTTP server running on port 8080 of a droplet. I have a load balancer pointing at this droplet.

Here is the configuration in the load balancer:

Load Balancer      Droplet
HTTP on port 80    HTTP on port 8080
HTTPS on port 443  HTTP on port 8080

I have SSL redirect turned off.

If I do a curl on my http://domainname/, I get a valid response back. If I try https://domainname/, it hangs for 20s, but eventually I get a 503.

Does anyone have any suggestions?

Hi. I thought I already commented further on this, but it appears I forgot to.

No, I never ended up working this out - it just magically resolved itself. I didn’t change anything, and I woke up a few days later and it was working. It doesn’t give me great confidence in the product (especially with the lack of any official comms from DO after a support enquiry).

So yeah… I guess just wait it out, is the best I can offer.

I’m also having this issue. @domlebo70 @atgreen have you been able to work this out?

Did you figure this out? I am experiencing the same thing.

I am experiencing similar problems. My current load balancer settings are as follows:

http on port 80 -> http on port 80 https on port 443 -> http on port 80

I’m using Let’sEncrypt certificate. My subdomains point to my load balancer IP.

Inbound rules for firewall have been open for port 443 and port 80.

Any advices is appreciated.

Hello,

Have you configured a port for SSL on the Droplet(not the load balancer)? If yes, you should use that for the HTTPS connection from the load balancer.

Usually in these cases, you can use port 8080 on the droplet for HTTP connections and 8443 for HTTPS connections. Of course you need to open the mentioned port and configure your Load Balancer so that I knows what InstancePort and Protocol it should use.

If you are experiencing difficulties, post the configuration files here so that I can give you a more in depth advice.
