I’m trying to post on wordpress using n8n, I’ve watched some videos, I checked the documentation available for n8n and when generating the app password on wordpress it doesn’t connect to n8n.
It seems to work fine for me too (self-hosted). Just making sure: you entered the base url of your WordPress instance - not something like domain.com/wp-admin?
Are you by any chance using any caching solutions, either inside our outside of WordPress? On my own self-hosted WordPress instance I use W3TC, Varnish and Cloudflare and I could reproduce this issue. By adding some random junk to the URL (like https://site.com?v=12345) I could bypass the caching and succesfully set up the new connection.
