I've seen this error before @Alban Vicarini . I've seen it been the result of a firewall connection or a resource exhaustion; so, one of the ends of connection had a failure at some point for whatever reason. But I believe this is more than likely a transient issue. If you have more logging, please feel to post it below. Since the difficulty was with a VS Code deployment, the deployment logs /deployments/ for any additional errors that may have proceeded ECONNRESET. If nothing is there, trying deploying via a different method like az webapp deployment or az webapp deploy. If this also fails, then it's an indication there's a transient issue with the worker your app service is running on. Normally, issues are resolved rather quickly but if it's persisted, do let me know down below.
