Invalid CSRF on dev install

[phenomlab]

Hi. I've setup a new domain at https://sudonix.dev to mirror my production domain of https://sudonix.com. I've completed the installation, recovered the database, and now have the dread invalid csrf token error - see below

invalid csrf token

I've reset all plugins, so it's not that. My nginx config doesn't seem to make much difference in the sense that if I switch proxy_set_header X-Forwarded-Proto https; with proxy_set_header X-Forwarded-Proto $scheme;

This is running on the same server as production, therefore, the port being used is 4571

I've seen multiple posts concerning this, and none of the fixes stated seem to work for me. If I run from another browser, or in incognito mode, nothing changes. Completely unable to login.

Fixed

I should have remembered that this database is from PROD, therefore, the cookie domain would need to be deleted. Issuing db.objects.update({_key: "config"}, {$set: {cookieDomain: ""}}); in the target DB under MongoDB, then restarting nodebb resolved the issue.
