Salesforce V2 Source — ComputeService — connector won't start

My Salesforce V2 source (JWT auth) was working fine and suddenly stopped with ComputeService:ApplicationInErrorState. The connector crashes during initialization before making any outbound network calls.

  • Error occurs at ComputeServiceSessionInitializer.initialize()
  • Zero egress telemetry (no network calls attempted)
  • Created a brand new source with fresh credentials — same failure
  • Salesforce org is live, user active, certificate valid (2 weeks old, PFX format)
  • All egress policies approved and correctly configured
  • No changes made on my side before the failure started
  • Environment: Developer Tier

Has anyone else encountered this? Is there a known issue with the Salesforce V2 connector or compute service on Developer Tier?
