worker SSL issue - trust anchor not found

đź‘‹ Hello! We're using a cloudflare worker at {subdomain}.{my-project}.workers.dev - and some android clients are rejecting the SSL with CertPathValidatorException: Trust anchor for certification path not found.

These are all android 9+ , so I dont think it has to do with any of the Lets Encrypt changes ... but we dont control that workers.dev SSL cert, its managed by Cloudflare... so I don't really even know what to look at next as to why its not liking the SSL.

not sure if related, but other machines are failing with `Unable to resolve host "{subdomain}.{myproject}.workers.dev": No address associated with hostname” - but the vast majority (30,000 per day) are fine. Seems to be some sort of a DNS issue, not sure if related.

Thanks for anything you can point me to! ✊
