Are you sure you got the right URL? Can you share a screenshot of your service’s deployments page?

Try removing the domain then adding it back, as well as redeploying.

I did remove the domain and add it back in and redeployed.

I used postman to try to test my api endpoints and went through all the things until they said to post this problem here. I had that app working but it was three years ago. I updated to node 20 from 18. I was (and still am) getting a CORS error when I try to use the app. (https://oracle-reading.netlify.app/) In addition to the 404.

its likely a stale port issue from a previous build try checking your public domain port and re assigning it, or clearing out the old port configs and ensurings its pointed at the right port. the CORS issue could be casued from a 404 on the OPTIONS call which would fail cors and fixing the port could also fix this issue. if the routing gets fixed but the port is still broken try adding the Netlify origin (https://oracle-reading.netlify.app) to the API's Access-Control-Allow-Origin config.
