403 error when trying to login

[codecowboy]

I'm getting a 403 response header from Apache when a user tries to log in:

403 Forbidden

NodeBB version is 1.0.3

The user facing login screen shows:

Failed login attempt, please try again.

Forbidden

The NodeBB log shows:

26/7 09:31 [26144] - error: /login
 invalid csrf token

I have tried:

Restarting nodebb & apache
Adding the following to apache config:

RequestHeader set X-Forwarded-Proto 'https'

In my particular case, this seems to have been caused by one or all of:

1. Missing the following request header in Apache:

<VirtualHost *:80>
    RequestHeader set X-Forwarded-Proto "http"
    …
</VirtualHost>

I added the above apache directive and restarted apache..

2.Having the cookieDomain set in the admin panel

If you cannot log into your forum, the only way to do remove this cookieDomain value is to manually run a DB query to remove it. In my case this was Mongo and I used a GUI client to remove the value.

A raw query would look something like this:

db.objects.update({_key: "config"}, {$set: {cookieDomain: ""}});
