Hi,
Thank you for your reply. I had tried with permission and all ok. I had done same thing on my other server before.
I did not found any solution for 502 Bad Gateway. Written access for whois folder ? Here is my permission details.
drwxr-xr-x 4 user1 user1 4096 Oct 29 02:14 .
drwxr-xr-x 3 root root 4096 Oct 14 10:37 ..

For my last question I had asked that my site coming like example.com:8080 on this address , If I try without port like example.com or with www like www.example.com then site is not coming. Only coming for example.com:8080 mean with port site is coming. Is that clear now? Please advice
Thanks

Not really, but post your Nginx configuration as well. Hard to see what you’re trying to achieve without it.
