Setup using NGINX base url

[bserrao]

I'm having trouble getting this to work in NGINX. (Already searched issues and google... tried some configs without sucess..)

I've followed the installation instructions, and i'm running the app with

node ./tiddlywiki.js Wikis/BobWiki  --wsserver

I can't have subdomains in this machine so i using /wiki/ location on nginx
This is my latest config... I can see Bob tiddlers, but i can't save any new tiddlers.

location /wiki/ {
                proxy_pass http://127.0.0.1:8080/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
}

On chrome i can see this errors:

The first 404 i don't know why is happening, but then i can see a call to /api that doesn't have the /wiki base url.
I've tried to add "proxyprefix" : "wiki" to the settings.json file also with no visible changes.

Could someone please point me in the right direction?

Thanks
