Refreshing DNS on a LEMP Droplet

Hi DO Community,

I’m in the process of moving a client’s website from an old hosting to the DigitalOcean.

Setup: LEMP on Ubuntu 20.04 (+ Wordpress, phpMyAdmin)

1. I installed and configured SSL certificate (generated with the certbot, --certonly option) on NGINX.

2. DNS is configured thru DigitalOcean’s Networking panel.

3. Domain is registered by DirectNic and DNS is set to DigitalOcean’s thru their dashboard.

Issue:

When I run curl -v https://mydomain.io within the droplet I get

*   Trying 74.117.219.199:443...
* TCP_NODELAY set
* connect to 74.117.219.199 port 443 failed: Connection refused
*   Trying 74.117.219.198:443...
* TCP_NODELAY set
* connect to 74.117.219.198 port 443 failed: Connection refused
* Failed to connect to womaneze.io port 443: Connection refused
* Closing connection 0
curl: (7) Failed to connect to mydomain.io port 443: Connection refused

The IP address is not correct. It points to the old DNS handled by DirectNic.

I can confirm that my browser (after clearing the DNS on my laptop) hits a new IP using the same command mentioned above and loads the website with a valid SSL certificate.

Thanks to the Wordpress’ Site Health Status page I discovered a several Critical Issues which are related to this particular problem and would really appreciate any help/idea on how to fix this DNS issue (within the droplet).

P.S. Just for the reference… Issues reported by Wordpress:

1. The REST API encountered an error (cURL error 7: Failed to connect to womaneze.io port 443: Connection refused (http_request_failed))

2. There are problems with the HTTPS connection of your website

3. Your site could not complete a loopback request (cURL error 7: Failed to connect to womaneze.io port 443: Connection refused (http_request_failed))
