Intermittent Certificate Errors for Retool Requests

We've rolled out the fix and verified that customers should no longer be seeing self-signed TLS certificate errors and that custom-domain provisioning capability has been restored.

We've confirmed that the issue has stabilized. We're monitoring for unexpected spikes in errors, but please anticipate a very low rate of errors until a permanent fix has been executed.

We've implemented a stopgap to prevent this issue from reoccurring while we wait to execute a permanent resolution. You may continue to very rarely see this self-signed cert issue.

Retool occasionally incorrectly returns a self-signed TLS certificate on a small subset of HTTP requests. This can manifest on any request, affecting normal usage as well as Workflow runs that run resource queries. Our team has identified the issue and is working on a resolution.

To address this, the Retool team has intentionally degraded the functionality to create a new custom domain. When creating a custom domain, certificate creation will take longer than usual while this incident is active. Your custom domain creation will progress automatically once this issue is resolved.
