Getting my API domain to be HTTPS

I have a website ( hosted at Namecheap, it uses cloudflare & is HTTPS.

I have a server with digitalocean where I run my api, I added my domain to it so will resolve to my flask api. When I send a HTTP request from my web app ( to I get a ‘Mixed Content’ error, needs to be HTTPS (or my Flask Application does atleast). I have been looking to see how I can get certificates for Flask and I saw DigitalOcean offers certificates for your domains.

I made a new certificate for my domain & subdomain but I don’t know how I am going to make my Flask app run on HTTPS.

Hi there,

What I could suggest is using Nginx as a reverse proxy for your Flask application. That way you will be able to add a Let’s Encrypt SSL using certbot.

You can follow the instructions on how to do that here:

Hope that this helps! Regards, Bobby
