Yes we also see this on a cron that runs every minute every couple of days or so "URL_UNREACHABLE-UNREACHABLE_CONNECTION_RESET. Original HTTP response code number = 0" it's a slightly different error message though, not a 500

Thanks for the response @ContinueAsGuest for the additional info! That seems not ideal as to your point other cloud platforms generally use the startup probe per instance to determine when to route traffic to itThe only other thing that comes to mind...

We are also noticing this with our cloud run service, would be interested to hear if anyone has solved for this
