What error do you see on the server? NodeBB has crashed, hence you see the 502 error served by nginx.
Nodebb mongodb default username and password for admin
I just finished installed nodebb with mongodb and noticed no default username and password for admin. How do I create one?
What version of MongoDB is installed?
Admin credentials are created as a part of the NodeBB setup process
I re-ran ./nodebb setup and it worked. Thank you!
@Syleron, good to hear. Happy to have helped!
