# App Platform Support

Generated on 18 Mar 2026

App Platform is a fully managed Platform-as-a-Service (PaaS) that deploys applications from Git repositories or container images. It automatically builds, deploys, and scales components while handling all underlying infrastructure.

[How do I fix the error "Record is managed by an App on this account, and cannot be deleted"?](https://docs.digitalocean.com/support/how-do-i-fix-the-error-record-is-managed-by-an-app-on-this-account-and-cannot-be-deleted/index.html.md): Use the app’s Settings tab to remove domains associated with App Platform apps.

[Why do I get the error “JavaScript heap out of memory” during deployment?](https://docs.digitalocean.com/support/why-do-i-get-the-error-javascript-heap-out-of-memory-during-deployment/index.html.md): Increase the heap memory by setting the environment variable NODE\_OPTIONS=–max-old-space-size=4096.

[How do I fix a "permission denied for schema public" error in my dev database?](https://docs.digitalocean.com/support/how-do-i-fix-a-permission-denied-for-schema-public-error-in-my-dev-database/index.html.md): Delete the existing dev database and create a new one. Then make sure that the app deployment completes successfully.

[Why do I get the error "Domain Already Exists" when trying to add a domain to an app in another account?](https://docs.digitalocean.com/support/why-do-i-get-the-error-domain-already-exists-when-trying-to-add-a-domain-to-an-app-in-another-account/index.html.md): You cannot add the same domain name to multiple apps or split an app and domain name across more than one account.

[How do I fix an "Image or digest not found" error with multiple registries?](https://docs.digitalocean.com/support/how-do-i-fix-an-image-or-digest-not-found-error-with-multiple-registries/index.html.md): Specify the registry property in the app spec.

[My container-based app fails to deploy without logs or error codes.](https://docs.digitalocean.com/support/my-container-based-app-fails-to-deploy-without-logs-or-error-codes./index.html.md): Troubleshoot by making sure the Dockerfile and its commands build on Linux AMD64 and other steps.

[How do I generate my app's SSL certificate?](https://docs.digitalocean.com/support/how-do-i-generate-my-apps-ssl-certificate/index.html.md): App Platform automatically generates and issues the SSL certificate during the configuration.

[Why am I receiving 520 status codes from my app?](https://docs.digitalocean.com/support/why-am-i-receiving-520-status-codes-from-my-app/index.html.md): Your app may have crashed while trying to receive an upload or return a response larger than it has been configured to manage.

Pay your balance to lift restrictions on actions you can take on the platform.

[Where can I find the client IP address of a request connecting to my app?](https://docs.digitalocean.com/support/where-can-i-find-the-client-ip-address-of-a-request-connecting-to-my-app/index.html.md): You can find the client IP address of a request connecting to your app in the `do-connecting-ip` HTTP header.

[Why is my app's database connection timing out?](https://docs.digitalocean.com/support/why-is-my-apps-database-connection-timing-out/index.html.md): Timeouts can be caused by high CPU utilization, so check your app’s CPU utilization and consider scaling your app.

[Why can't I route traffic to my app's dedicated egress IP address?](https://docs.digitalocean.com/support/why-cant-i-route-traffic-to-my-apps-dedicated-egress-ip-address/index.html.md): Dedicated egress IPs route egress (outbound) traffic from an app. To route ingress (inbound) traffic to an app, use one of App Platform’s public ingress IPs.

[Why is my app not resolving .gov domains?](https://docs.digitalocean.com/support/why-is-my-app-not-resolving-.gov-domains/index.html.md): Use a custom DNS resolver or contact the domain administrator, as some .gov domains block DigitalOcean IP ranges and prevent App Platform apps from resolving them.

[Why can't I find my app even after paying my past due balance?](https://docs.digitalocean.com/support/why-cant-i-find-my-app-even-after-paying-my-past-due-balance/index.html.md): If your resources have been destroyed due to a prolonged past due balance, you can contact support to request the app spec for deleted apps to recreate the app with the same configuration.

[Why are there multiple 408 errors in App Platform's runtime logs?](https://docs.digitalocean.com/support/why-are-there-multiple-408-errors-in-app-platforms-runtime-logs/index.html.md): Multiple 408 errors are often caused by your app sending health checks with very short timeouts to App Platform. They typically don’t affect the functionality of the app.

[Why is my App Platform build or deployment failing with an out of memory error?](https://docs.digitalocean.com/support/why-is-my-app-platform-build-or-deployment-failing-with-an-out-of-memory-error/index.html.md): App Platform builds have a fixed amount of memory available, so try optimizing your builds to stay within the 8 GB limit. You can increase the amount of memory in App Platform deployments by upgrading to a different plan.

[How do I back up my dev database on App Platform?](https://docs.digitalocean.com/support/how-do-i-back-up-my-dev-database-on-app-platform/index.html.md): Dev Databases have no direct backup feature but you can use a cron job to back up your data to another database.

[Why are my App Platform environment variables not updating?](https://docs.digitalocean.com/support/why-are-my-app-platform-environment-variables-not-updating/index.html.md): Component-level variables override app-level variables, so you may have defined environment variables at both levels.

[Why are large files failing to upload to my app on App Platform?](https://docs.digitalocean.com/support/why-are-large-files-failing-to-upload-to-my-app-on-app-platform/index.html.md): Your upload may be exceeding your app’s allotted file storage space or it could be timing out.

Use `dig` to see the dynamic IP address of the app.

[Why does my app keep restarting on App Platform?](https://docs.digitalocean.com/support/why-does-my-app-keep-restarting-on-app-platform/index.html.md): Application crashes, high memory consumption, and high disk usage are usually responsible for apps restarting.

[How do I add an A record to my app on App Platform?](https://docs.digitalocean.com/support/how-do-i-add-an-a-record-to-my-app-on-app-platform/index.html.md): App Platform provides two static ingress IPs you can use to map A records to your app.

[Can I inject certificates or other files into my app at build time?](https://docs.digitalocean.com/support/can-i-inject-certificates-or-other-files-into-my-app-at-build-time/index.html.md): App Platform does not currently support injecting values as files on disk. Use environment variables to create files at run time.

[My app failed to build and I received an exit code](https://docs.digitalocean.com/support/my-app-failed-to-build-and-i-received-an-exit-code/index.html.md): Review your app’s build logs to diagnose which process failed during building.
