Hi, I have a 15 server with a 15 keycloak-installed-adapter I’m trying to migrate to 18. On the 18/Quarkus server side, I can connect to /account with my user. However, on the client side (desktop app), I’ve upgraded the library to 18 and removed the /auth, but keycloak-installed-adapter gives me a “Page not found” from the /protocol/openid-connect/delegated URL. I have debug logging turned on, but don’t see any errors. Thanks, Carl ---

Please post any logging or troubleshooting suggestions. I don’t see anything coming through on the console in either “start” or “start-dev” mode. The browser says “We’re sorry. Page not found”. Nothing in the browser console either ---

I think this issue is what I’m experiencing. The token looks good, but I land on an error page instead of “Successful” https://github.com/keycloak/keycloak/issues/9401
