I am new to n8n so please be aware of my newbie status. I installed docker on my Synology NAS to experiment with n8n. I successfully ran the container and added security to the container using environment variables.
The Synology ds220+ Nas is running on my routers DMZ so it can be seen outside my network. As a result n8n is accessible to the world using this address
I am having trouble though with using Dropbox and LinkedIn apps. After setting up Dropbox with an app and API key I cannot get the authentication to validate and am getting an error “Dropbox credentials are not valid”
I have confirmed them twice and the API key is correct.
I tried adding a LinkedIn app and I get the same error except here the authentication opens up a window that attempts to call the callback URL and my setup is using localhost:5678 for the oAuth url. Is there a way to reconfigure that in n8n?
