Hello.

I have a website on digitalocean and I just followed the tutorial down below so i got my certificate and now my website uses https protocol.
https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-20-04

Everything is good to this point.

But there is a but. :)

I’m using node.js on my website. It connects to my mongoDB cluster and it creates an api url based on my domainname or/and droplet IP address.

For example my API_URL is: 123.45.67.89:5000/items
I fetch that URL and do somethings on my website based on items.

But as i followed https protocol tutorial, i just enabled my firewall and because of that i guess, firewall is blocking my API URL and i get error on fetch.

I also can’t reach that API_URL(123.45.67.89:5000/items) manually.

While firewall is closed i can fetch my api.

What should i do?

Thanks.
Regards.
