"cURL error 28" errors in the WordPress diagnosis

Hello people!

I recently installed EasyEngine V4 on a $ 5 droplet with Ubuntu 20.04. The installation proceeded smoothly. However, when accessing the WordPress control panel, I noticed that WordPress Diagonosis found two errors.

The request to the REST API failed due to the following error.
Error: cURL error 28: Connection timed out after 10000 milliseconds (http_request_failed)

The loopback request for your site has failed, which means that features that depend on it are not working as expected.
Error: cURL error 28: Connection timed out after 10001 milliseconds (http_request_failed)

Should I worry about these mistakes? Is it possible to correct them?

Thanks for the help, right now!

Okay, I finally figured out what was causing this error - it wasn’t in EasyEngine - and how to fix it.

I didn’t realize that this was a UFW problem that I had activated on the server before installing EasyEngine. Anyway, I managed to solve with the commands:

ufw allow 80
ufw allow 443

So, if you have a situation similar to mine, maybe opening ports 80 and 443 on the firewall should be the solution.
