Hi,
I'm trying to deploy an app using the reflex python library, but after the app compiles successfully, I get the error above. I have tried having the app listen to every port, including 80 and 443, and it doesn't fix the issue.
Thanks.

Good morning,
Been looking for similar reports of this, we've been experiencing this since Sunday evening on the 5th May.
Started in our production service (no changes or deployments have been made in months just to add).
Whilst we were investigating production, our uat and pre-production slots started to fail in the same manner.
Our production slot came back online on Tuesday, and overnight has now failed again.
Currently our PREPROD slot has come to life again. All this without any changes.
All we've found is that Microsoft are running some planned maintenance, but at no point does it suggest it could lead to this kind of outage. https://portal.azure.com/#view/Microsoft_Azure_Health/DetailsPage.ReactView/fromDeeplink~/false/index~/0/selectedEventSummary~/%7B%22trackingId%22%3A%22WMNJ-7PZ%22%2C%22scope%22%3A%22Subscription%22%2C%22impactedSubscriptions%22%3A%5B%22e471fc84-ecdf-4123-af12-5e8b2c7d1cc5%22%2C%22bb1b30bc-86a8-4469-a3a1-438a0e70f480%22%5D%2C%22eventType%22%3A%22PlannedMaintenance%22%2C%22impactStartTime%22%3A%22Thu%20May%2002%202024%2021%3A05%3A19%20GMT%2B0100%20(British%20Summer%20Time)%22%7D/trackingId/WMNJ-7PZ/impactedSubs~/%5B%22e471fc84-ecdf-4123-af12-5e8b2c7d1cc5%22%2C%22bb1b30bc-86a8-4469-a3a1-438a0e70f480%22%5D/scope/Subscription/eventType/PlannedMaintenance/impactStartTime/Thu%20May%2002%202024%2021%3A05%3A19%20GMT%2B0100%20(British%20Summer%20Time)
We've concluded this is absolutely no way anything we have control over now, we've tried every possible option regarding ports, investigating issues in our app starting up, everything. Nothing works.
This 100% has to be microsoft azure.
The issue we get across all slots is below:

Just to confirm the container logs it refers to do not container anything else other than the logs in the console as above. Absolutely blind, if this continues we'll be lifting this out of the App Service and planning migration to another provider or on prem VM over the weekend.
Unfortunately as we utilize a third party cloud managing company, we are awaiting them raising tickets with Microsoft so our hands have been tied majorly.

It is not possible to deploy an Web App application using a Reflex UI, as it requires to expose two ports in a docker custom container. The App Service does not support exposing more than one port. An alternative solution will be to use the Virtual Machine service from Azure.
Hi @Rivas, Mariolys we are sorry to hear you're facing this issue.
The error message "Stopping site <site name> because it failed during startup" means an issue during the startup process of your application deployed on Azure App Service. While you mentioned trying different ports (80 and 443), the problem likely lies elsewhere. Here are some steps to troubleshoot and fix this issue:
Since you're using the Reflex library, there might be more specific error messages logged during deployment. These logs could be stored in Azure Application Insights or Kudu logs. Access the Azure portal and navigate to your App Service resource. Look for "Application Insights" or "Kudu" to access the logs. These logs might provide clues about the root cause of the startup failure, such as missing dependencies, configuration errors, or exceptions within your Reflex application.
Also, The issue might be that your site is not starting up within the default time limit of 230 seconds. You can try increasing the startup time by setting the WEBSITES_CONTAINER_START_TIME_LIMIT App Setting to a higher value. The maximum value you can set is 1800 seconds.

Solution:
"it is not possible to deploy a web App developed with reflex UI. The python reflex is suing frontend and backend on the same application has exposing two ports in a docker custom container. As of now, App Service doesn't support exposing more than one port on custom container. So, it is not possible to run the application using custom container.
An alternative solution would be to use a Virtual Machine service."
Best,
Grace
