Question
Couldn't fetch api while firewall is enabled.

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.

Hi, Since you followed the tutorial, I guess you configured firewall rules using ufw management tool. If I am right, list the rules and check if communication is allowed on port TCP 5000
If it is not allowed, you can allow it adding a rule:
