App Service deployment is failing with status code 409

Dekker, Robbert 0

Since yesterday our API deployments are failing with the following error code:

##[error]Failed to deploy web package to App Service.##[debug]Processed: ##vso[task.issue type=error;]Failed to deploy web package to App Service.##[debug]Deployment Failed with Error: Error: Error: Failed to deploy web package to App Service. Conflict (CODE: 409)##[debug]task result: Failed##[error]Error: Error: Failed to deploy web package to App Service. Conflict (CODE: 409)##[debug]Processed: ##vso[task.issue type=error;]Error: Error: Failed to deploy web package to App Service. Conflict (CODE: 409)##[debug]Processed: ##vso[task.complete result=Failed;]Error: Error: Failed to deploy web package to App Service. Conflict (CODE: 409)

We see that there aren't any other deployments currently in progress, still we see this error. Would really appreciate any help I can get.

Already tried:

Scaling up the App Service plan
Restarting the App Service plan
Moving over apps from the App Service plan to another to free up space

@Dekker, Robbert Thanks for reaching out to Microsoft Q&A, apologize for any inconvenience caused on this.

Could you please help me with more information try the suggested steps and let me know if you have any further questions on this.

Are you deploying your application code using visual studio or using any other deployment methods GitHub or zip deploy?

Try Restarting Kudu via the SCM portal (using Advanced tools) Kill w3wp process via process explorer this will cause down time to your app service.

Have you tried start and stopping the app service and retried the deployment and still facing the issue?

If you are still facing the issue, please send an email with subject line “Attn:Venkatesh |thread title” to AzCommunity@microsoft.com referencing this thread with your Azure subscription ID and WebApp details, I will follow-up with you.
