Connection problem while hosting multiple tor sites on same device

Question

I am trying to host two tor websites on the same device. The original one works but not the new one. I have followed the steps in here but I can't connect to the server.

I've added a mew serviceDir and Port in /etc/tor/torrc

#this site works
HiddenServiceDir /var/lib/tor/hidden_service/
HiddenServicePort 80 127.0.0.1:8080

#this one does not
HiddenServiceDir /var/lib/tor/hidden_service2/
HiddenServicePort 80 127.0.0.1:8081

and in /etc/nginx/sites-enabled/default I've added

server {
        listen 8081 default_server;
        listen [::]:8081 default_server;
        root /var/www/html;
        index index.html index.htm index.nginx-debian.html;
        server_name _;
        location / {
                try_files $uri $uri/ =404;
        }

running nginx -t gives no error

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

I am at a loss here. Any help is appreciated!
