New install leaves me with session mismatch + invalid csrf

[metalkramp]

Seems like similar error which I've been experiencing lately (although I'm not using CentOs): https://community.nodebb.org/topic/9886/invalid-csrf-token/3

Perhaps we can figure it out together. Have you tried using older version like 1.1.2?

[tin]

I am seeing the same issue here. I have tried 1.4.0 with both Node 7.2.1 and 6.9.2 on a Ubuntu VM with Redis.

The problem seems to be with the url. NodeBB does not seem to like https://domain.com url. It worked fine when I reverted back to the default http://localhost:4567 but using the localhost URL means assets required by plugins such as emoji are not serving correctly.

This seems to be a pretty critical bug. Any way to prioritize a fix for it?

Thank you!

[yariplus]

What are you using for your url in config.json?

[tin]

This is the value of url I was trying to use: "url": "https://forums.coinfetch.com".

[yariplus]

@tin Are you using nginx or apache? Can you post your config.

@yariplus

We're using Nginx. Here is the config

Are you running the server behind an AWS load balancer?

[julian]

Your nginx config suggests it is listening on port 80, whereas your config is set up with https... that will cause a session mismatch error.

[tin]

@julian @yariplus - yes, we are running behind a load balancer listening to https. Is that an issue?

[julian]

@tin If your load balancer terminates SSL and proxies the connection to nginx (and NodeBB) as http, then nginx is telling NodeBB that the protocol is HTTP when it should be HTTPS.

proxy_set_header X-Forwarded-Proto $scheme;

Change this to https and try again?

[tin]

@julian, that did the trick. Thank you so much!

I have never gotten this new install to work. It is extremely frustrating.

I have an older install, that is on 1.2 or 1.3, that I upgrade to 1.4.0 and it started having the same problems, so I reverted to the snapshot I had made of that VM prior to upgrading.

I am going to delete the new VM and start over one more time.

[JaredBusch]

So I have the site working. I did not have this line in my Nginx config. My Nginx is on a different host, not the same one.

proxy_set_header X-Forwarded-Proto $scheme;

But I have never had it and the previous existing sites have worked.

It also does not explain why I received the error on the existing install after an upgrade from 1.3.0 to 1.4.0

[julian]

@JaredBusch That's a new requirement -- surprised we didn't catch that it was missing in your config earlier

[Pramvir Rathee]

@JaredBusch said in New install leaves me with session mismatch + invalid csrf:

proxy_set_header X-Forwarded-Proto $scheme;

 server {
    listen 80;

    server_name www.docfindy.com;

    location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://127.0.0.1:4567/;
        proxy_redirect off;
        proxy_set_header X-Forwarded-Proto $scheme;

        # Socket.IO Support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
server {
    listen       80;
    server_name  docfindy.com;
    return       301 http://www.docfindy.com$request_uri;
}

I am using Mongo 3.2 and Nodebb 1.4.2, this is my nginx config file, session mismatch still present, plaase help.
