Start with the three linked Community Toolkit Aspire Actions runs and compare the failures around the `Service dbgate should have valid address at this point` exception. Trace the relevant service-address handling from the failure logs, then establish a reproducible diagnosis or capture enough additional diagnostics to explain the sporadic error and verify that services have valid addresses.
