Iptables blocks any connection ports 80 and 443?

Hi everyone.
I want to ask you a question about wordpress on a server with hestia.

Apparently everything seems to work fine except for the WP-super-cache plugins and a BulletProof Security WordPress security plugin.

These generate an error and it seems that they make requests for port 80 and 443 to some API.
There is some configuration in hestia’s iptables to block API requests through the port. 80/443???

I can’t find guidance, I’ve looked a lot on the net without success and I have to ask here.

They know what could be the reason.

Thank you

Hestia does not block any outgoing traffic over port 80 or 443.

Hello, I have not formulated my question well.
I have created a new server with hestia, I have installed wordpress again and the error persists with some plugins.
Of the kind:
cURL error 7: Failed to connect to domain .com port 80: Connection refused
cURL error 7: Failed to connect to domain .com port 443: Connection refused
