We use keycloak in a standalone manner deployed via docker-compose behind a nginx/LE reverse-proxy. This has been fine until the release of version 16. Typically, all we have to do is change the docker image tag version in the docker-compose.yml file and the upgrade goes fine. This was not the case for version 16. I understand theree may be some steps we need to take for the Wildfly upgrade, but I am not sure what those are within the parameters of docker.
Here are the logs I get when all I do i move from 15 to 16 in the docker-compose file

I have reviewed this topic: Migration from docker 15 to 17.0.1 - #3 by stumkar
But I was unable to decide how best to apply the mentioned fix, or if it even applies to my use case.
