Page 502’s then loads, then 502’s and can’t use any of the routes. So confused.
Hey @Mendddd ! Is it your application that’s giving the 502? 502s are server side errors, so your app could be under load, have some misconfiguration in the DNS, or it could be giving invalid responses. Do the logs show any errors you could pursue? To look at logs, use flyctl logs.
Nothing in the logs and I just checked using the generated hostname with {projectname} .fly.dev and it’s working fine, the app is behind cloudflare and using the normal url it’s where it’s 502’ing.
Okay seems to be generating some logs now, I have another app running on fly fine, it’s svelte with node, but this is express with node and not working

Those logs look fine, and without seeing your app, it is hard to make recommendations, so instead can you try deploying the following:
mkdir demo
cd demo
npx --yes @flydotio/node-demo@latest
If you can successfully deploy the demo app, the question then becomes what is different between that app and yours? If it helps, the deployment app can be customized to more closely match your application: Vanilla with Candy Sprinkles · The Fly Blog
I can privately send you a gist if that’s more helpful.
Okay, I’ve sent an email and now building the demo, will see in a sec
demo deploys just fine and I don’t see much difference between mine and the demo other than one uses ejs and one is using tmpl same package.json + deps, same dockerfile basically.
You can configure the demo to run with ejs by passing --ejs as an option. See blog entry for details.
When I comment out your const connection = and connection.connect( lines, I can launch and deploy your app. Relevant information from the logs:

so why would the database be dying here? I have fed the secrets… :\
Any relevant information in the logs? Try fly logs or go to the dashboard for your app and click on monitoring in the left hand sidebar.
I’ll just take a wild guess here. If your database requires ssl, you may need to add the following to your connect call:
ssl: {
ca: readFileSync("/etc/ssl/certs/ca-certificates.crt")
}
And then use this to modify your dockerfile:
npx dockerfile --add=ca-certificates
