I have a weird problem. I set up my droplet and domain yesterday. I bought the domain on Hover and redirect it to Digital Ocean name servers. I’m using Nginx and Ubuntu 16.04. Everything worked fine but after some hours, I had this error when trying to access my website: allodocteuronline.com doesn't allow connection... ERR_CONNECTION_REFUSED. I don’t always get that error but only sometimes. Another weird thing is sometimes, the Hover default web page is displayed as if the DNS is not propagated yet. I don’t see any error when analyzing my SSL with ssllabs.com. There is no error when I run sudo nginx -t. But I have this error in /var/log/nginx/error.log:
