Known Issues in Ambassador Edge Stack


  • TLS certificates using elliptic curves were incorrectly flagged as invalid. This issue is corrected in Ambassador Edge Stack 2.2.2.


  • If Ambassador Edge Stack's Pods start before Redis is responding, it may be necessary to restart Ambassador Edge Stack for rate limiting to function correctly.

  • When using the ACME client provided with Ambassador Edge Stack, a delayed ACME response can prevent the Host using ACME from becoming active.

    • Workaround: Make sure you have a wildcard Host that does not use ACME. The insecure routing action doesn't matter: it's fine for this Host to redirect or even reject insecure requests.
