Heroku is free ?

That's it, I come across this on freenom, then I have some indications?

@whimpers Thank you for your help, I'll do this tomorrow!

@juan-g Ok yes, I have to inform the local IP or that of my box?

@whimpers No ! Can you explain to me how?

Thank you for taking the time to explain. I would like to host it on my pc, I took a domain name on the internet already, nginx was configured as on the documentation (Ubuntu (recommended)) everything was well done, but at the moment I try to access my site it does not work (http://hyunforum.cf) I just wish to have an explanation, steps that I will miss and that are not specified on the documentation ..

@juan-g On my computer

Hello !
I'm a bit nil and I'd like to get into nodebb with my linux, I followed the installation steps as it should, but going on my forum link it does not work ... In local it works very Well, if I could get help from you, I'll be very thankful, thanks in advance...

@whimpers it seems to me ! the domain name must have been purchased?

Hello,
I followed the tutorial to use nodebb on my computer as vps, but going on the link defined during the configuration nothing happens, the forum works very well locally but not when I want to put it online.
It is a project that is important to me, if I could receive help for the launch of my forum nodebb from my linux I will be very grateful, thank you in advance!
