Why does RH-SSO server log a KC-SERVICES0067: failed to parse RestartLoginCookie error?
Issue
We just upgraded from RH-SSO 7.0.0 to RH-SSO 7.2.1 and we are seeing the following error:
2018-04-11 22:51:06,587 WARN [org.keycloak.keys.DefaultKeyManager] (default task-9) KID is null, can't find secret key
