Connecting fly.io to Google domain

[Eran]

I am trying to us google domain for my fly.io app as described here:
Custom Domains and SSL Certificates · Fly Docs

Unfortunately I am not able to access site via domain address (48 hours have passed)

Using dig I can see that the IPs are properly set:

[I] ➜ dig A picatap.com

Can you try to see logs for your app to spot any issues? picatap.com seems to almost load but never finish and so does your http://picatap.fly.dev/ too so that tells me it might be app-related.

Yep, I was pointing to a deprecated deploy and not the new one

Thanks !!!

I know it more of a google domains question :- ) can you think of why https://picatap.com/ is working while www.picatap.com is not ?

[lubien]

That’s a weird one. Im not sure what’s happening. Same as before the IPs are set properly (we can see that with dig) but this time it goes really fast to ERR_CONNECTION_CLOSED so maybe your app is terminating it?

For reference if we go to a gibberish non-configured domain such as https://lubien-would-not-buy-this.com we get ERR_NAME_NOT_RESOLVED, so that tells me either your app or Fly.io are terminating the connection? As far as I know we would not terminate the connection like this we even have https://www.fly.io/ hosted on ourselves and that’s just an app with a certificate.

[Eran]

When trying to access from www.picatap.com I don’t see any logs so I assume my app is not closing the connection, should i include a specific handling for www in my certificate ?

[Eran]

Issue resolved by creating additional certificate for “www.picatap.com”
Thanks

Ah, glad its working now!
