Pathania, Birender Greetings & Welcome to Microsoft Q&A Forum. Thank you for posting your query here!
Could you confirm in which region you are trying?
I just tried deploying a webapp in East US and its working fine.
The "Deploying web app" is keep showing.
How long its been showing this message?
What could be the possible reason for this behavior and how can I resolve it?
Please note that the deployment process may take some time to complete, depending on the size of your app and the resources you have allocated. Please be patient and wait for the deployment to complete
Could you check if there are any errors or warnings in the deployment logs. See Monitoring Azure OpenAI Service for more details on how to collect logs.
Do let me know if that helps or have any further queries.
