contour: envoy container in CrashLoopBackOff : error initializing configuration

Hi

we are deploying Contour (v1.11.0), with Envoy (v1.16.2) as a DaemonSet, using the following yaml templates : https://github.com/projectcontour/contour/blob/release-1.11/examples/render/contour.yaml

We only applied minor changes to fit our configuration (such as pointing to our local images repository, adding privileges for RBAC etc).

When firing up the helm installation, the Envoy pod fails with CrashLoopBackOff, with the following error in the envoy container :

this error wasn’t occurring with older versions.

Just for information, the contour-certgen job has been successfully run, and the Contour pods are up&running.

Can you please advise ?

Thanks
