Thanks for the help. Got it working with the below solution.

Like in Apache there is not serverAlias in nginx

We have to enter in .conf file like below

server_name mysite.com www.mysite.com;

i already have a CNAME entry like in the screenshot

yes i am

My site loads 'nginx welcome page' with www.mysite.com

when entered mysite.com it works fine and my homepage loads.

I pinged and dns works fine. How do i solve this? Thanks

Done.... a million thanks....i've been fighting with this for the past 4 hours. Finally asked for help

Yes here it is. the first screenshot is the error i get

Should i change any chmod permission to that folder

after logging into ssh i typed "sudo su username" and tried to create the file. still same issue pops up. I have configured for "superuser". Should i try it from "root user"

I am getting this error while trying to save the file

"error writing permission denied". I might have made some silly mistake somewhere

thanks for the help, how do i create a file in ssh. i am using digitalocean ubuntu server?

My site works fine in mysite.com:4657

I knew that i had to change the server name to make it work without ":4567" but when i go to

nano etc/nginx/conf.d/nodebb.conf its completely blank
. How can i solve this issue.?
