All you should really need to do is change the url value in config.json and change the server name in your reverse proxy.
Solved Facebook / Google SSO error
Hey i was checking the logs via ./nodebb log
this was the error generated
1/11 15:45  - warn: [plugins/nodebb-plugin-sso-google] Hook
filter:user.deleteis deprecated, please use an alternative
similar goes for face book as well.
is there a fix for this would appreciate it
Deprecated means its support will be dropped in future versions of NodeBB, but is working for now.
So it's no error you need to fix right away.
And since both are @julian s plugins you can be pretty sure it'll get updated before support-drop
