ERR_SSL_PROTOCOL_ERROR when making a request to my servers droplet IP

Hey guys,

I have been working on a project which I decided to upload to digitalOcean.

I have an App for my client and a droplet for my server. When I visit my clients webpage and I make a request to the server ( https://ipadress:80/api-route ) I get ERR_SSL_PROTOCOL_ERROR, same happens when I try to visit the route directly.

How I understand the problem is that my server needs to have an SSL certificate set up but as the server is just an IP adress and does not has a domain how will I be able to fix the issue?

Hi @bubblyturquoiseshrimp,

You can’t have an SSL certficate on an IP address. Additionally, you won’t be able to use port 80 and https together.

First, I’ll recommend using a domain name and secondly, if you need to use a specific port like so https://domain:80/443/9000 then I’ll recommend using Nginx as a reverse proxy as well.
