8.3 designer unable to open Ignition 8.0.4 GW

I’m getting the following error after upgrading the designer:

java.security.cert.CertPathValidatorException: Moderate verification enabled and an old gateway was blocked which does not support Signature Verification

There is a default signature verification check (set to MODERATE) that will prevent launching against gateway versions 8.1.33 and older. You can reconfigure this check in the launcher .json files to be LENIENT/LOOSE which will allow these “legacy” gateways.

Something to add here is this JSON file should be modified with all Designer Launchers closed, otherwise it will rewrite the original settings on exit.

This should say “LENIENT or LOOSE" unless i’m mistaken… using the literal string “LENIENT/LOOSE” gets overwritten with null. Setting it to LOOSE made mine start working

Yes, that's right, those are two different values.

The full list:

  • LOOSE - No revocation checks; allows unsigned jars for older gateways :warning:
  • LENIENT - Revocation checks not required (soft fail); allows unsigned jars for older gateways :warning:
  • AIR_GAPPED - No revocation checks at all; allows unsigned jars for older gateways :warning:
  • MODERATE - Enforces CertPath checks (except expiration) with soft-fail revocation checks
  • STRICT - Fully enforces CertPath checks (except expiration) including revocation checks ✓

(AI summarized obviously)

edit: ah that list is already in the linked docs!
