Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: www.chamakatech.com chamakatech.com

I ran this command: sudo certbot --nginx

It produced this output:- The following errors were reported by the server:

When I visit www.chamakatech.com, I see your ZTE’s router’s login screen.

You may need to re-assign its web UI port from 80 to something else, in order to properly port-forward the domain to your nginx server.

I still see the ZTE interface. You can try test with https://letsdebug.net, it uses fresh DNS every time, and it will show a warning if it sees the router interface.
