502errors could be caused due to multiple application level issues. Have you had a chance to run through this troubleshooting guide to begin with? Does the issue persist despite a restart?I'd suggest starting with the Diagnose and solve problems blade to quickly troubleshoot the issue and mitigate it. You can access the diagnostics tool on the left menu pane by navigating to your web app on the Azure Portal.
Please check and let us know your findings, and we can narrow it down further.

There where only two apps hosted in the service plan.

2021-09-03T13:31:09.037+00:00 @Vishnu Udayakumar Thanks for the response. Is it the case that you see issues only when attempting to deploy to your web app from Azure DevOps? Do any of the other publishing methods like Zip Deploy or FTP deploy work? Are you able to otherwise browse to and access your app normally without any issues?

2021-09-06T18:39:06.957+00:00 @Vishnu Udayakumar Thanks for the response. Could you please confirm if this is a Windows/Linux app? What is the current SKU and region where you have it deployed?
Request you to please check on the following:
- Since you're having issues with accessing the Kudu interface as well, please try scaling up to the next higher tier and re-trigger your pipeline/deployment. If it succeeds, scale back down to the original tier. This would indirectly restart your SCM sites as well.
- Set the system variable
system.debug=trueon your ADO Pipeline and check if there are additional details of the error. - Please check if the issue persists when you deploy it to a diffferent App Service from Azure DevOps, or just this one.
- Regardless of the current SKU, please check if your app is running into any of the prescribed limits (ex: file system storage, CPU Time etc.) for your tier. To verify some of these limits, naviagate to the Quotas blade for your app on Azure portal.
Please verify the above and let me know your findings for each step, and we can check on the next steps.
