here is my qovery yaml
name: “connector”
project: “connectorenv”
organization: “QoveryCommunity”
publicly_accessible: true

      • “/*”`

Hello. .qovery.yaml is not needed anymore for the V2. If you’re deploying in V1, you should move to the V2 as soon as possible as the V1 is getting shut down in 2 weeks. After that’s done, make sure you’re configuring the correct port in the Qovery settings by going to settings, port, then checking there.

I can access the domain you have specified, but it includes some Chinese characters, so definitely not an error.

Please let me know if you’re still running into trouble.

what do you mean by V1 and V2?
I am not sure on which I am
also the domain I added just for clarification, I haven’t thought there is a website with this domain :slight_smile:

I just confirmed it is V2

my problem still exists and I tried to change the port from the settings, and looks like this page is not working also

It is going to help to see your configuration without bothering you too much, so I can investigate

here is the link.

thanks in advance


this is the msg I receive when I set the port


Sorry for the late response, after investigating your case it seems we have a regression with custom domain in the V2.

It is going to be fixed tomorrow or next week if time is short.
I am going to keep you updated regarding the evolution.

Sorry for the inconvenience

thanks , how about the port issue

I managed to add it without any issue this morning.
Have you changed something ?

I just added the domain
The only problem I have is defaultbackend 404
I am not sure how to solve it
I uploaded the code on heroku on a2hosting
It is working fine there I am not sure why it’s not working here

It seems that you are getting a 404 default backend, because your app is not running properly
and is crash-looping

the code is working fine here
you can check it, also I tried it on Heroku it is working
but on the qovery I am not sure why is this error is happening in the first place, and I believe it is not from the code

moreover I tried to host another app that is working locally and heroku and got the same error

Hi @Mars-2030 ,

Are you sure you’re using the same commit on Heroku and Qovery?

Because here, from logs of your app shown by @Erebe , we can clearly see the issue is code side.

in your images, i can’t see if your app is deployed, if not, you need to deploy it, and check if you have credits for it. version 2 works on a credit basis.
