Version
26.2.5
Regression
[x] The issue is a regression
Expected behavior
I downgraded back to 26.2.4 and working fine again.
Actual behavior
Server is not starting
How to Reproduce?
I'm guessing it's something from my environment, but my keycloak is installed manually inside a container (LXC, Ubuntu 24.04), using postgres db (inside same container). Accessed using Nginx reverse proxy.
Here are my environment variables:
Environment="JAVA_HOME=/usr/lib/jvm/java-21-openjdk-amd64" Environment="KC_DB=postgres" Environment="KC_DB_USERNAME=XXXXXXX" Environment="KC_DB_PASSWORD=XXXXXXX" Environment="KC_HOSTNAME=keycloak.example.com" Environment="KC_HTTP_ENABLED=true" Environment="KC_PROXY_HEADERS=xforwarded"
Anything else?
