Question

My Azure Web App just says 'application error' everytime I click on the default domain

I have done everything right. I have added all the secrets needed, set up my GitHub workflows, built my docker image. And Have my workflow setup so it pushes to azure. But for some reason none of the content ever gets pushed. Help!
I am very new to Azure and I am sure I must be missing something, but I have no idea what to do.

Hi @Rhiannon Brönnimann

Thanks for reaching us regarding the application error for your azure web-App

Could you please confirm the following to help us identify the issue?

Are there any error messages or logs in Azure Portal, Log Stream, or Diagnostic settings?

Did you review the Deployment Center or GitHub Actions logs to verify the Docker image is being pushed successfully?

Are all necessary environment variables and secrets set up correctly in your Web App settings?

Does your Dockerfile work locally? Can you run the image without errors using the command below?
docker run -p 8080:80 <your-image>

Does your app rely on any external resources, such as databases or APIs, that might not be working?

Have you tried restarting the App Service or redeploying with a clean build and push?

Are you using the default domain, and is it mapped correctly, or are you using a custom domain?
