Website showing error on every topic/page

Hello All

My website applenow.io is having issues. Every page its showing connection error although website is up and updated.

It’s probably a plugin. Comment out any non-discourse-provided plugin in your app.yml and rebuild again.

categories and users load, just not topics, so it’s probably some plugin that does something to topics.

It has to do with the AI plugin and its attempt to do suggested topics. The plugin is broken or misconfigured. I’d try turning off the suggested topics feature in the AI plugin and then if you can figure out what causes the error, make a bug report about that.
