Error: failed to find request token in session

Hey if someone is still having the issue I have another solution...

add this code :

app.use(passport.session({ secret: 'Shhh.. This is a secret', cookie: { secure: true } }));

just add cookie: { secure: true } and it will work just fine...

I too had this issue and above technique helped me solve this.

... Sigh. I forgot I changed the subdomain. So, the cookie wasn't readable because the domain name was different.
