It should work read-only (disallow javascript and 3rd party cookies prevents everything else).
Node.js is just the server-side, it doesn't matter in this regard if the client disables javascript. But since NodeBB relies on javascript for login purposes, it's read-only then.
Some what, I found that after posting this but it leaves me further confused. I downloaded putty and I guess I am going to need a .pem file and some codes that were used when the instsnce was created atleast thats what I am understanding atm.... I will try again tomorrow and see if I can make sense of all this. Thanks for the help.
@julian Just works as intended.
The approach here totally works.
As you kindly suggested, it's my mistake not to have set subdomain by DNS.
I somehow misunderstood Ngynx takes care of subdomainsDNS IP routing, my bad.
Thanks a lot.
