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?
