Hello, everyone! My current setup: 2 Keycloak 2.5.4 servers in Standalone HA mode, MySQL 5.6.27 database hosted on Amazon AWS RDS. Recently, I've migrated my Keycloak servers from 2.1.0 to 2.5.4. I've copied "standalone-ha.xml" and "keycloak-server.json" to the new installation and ran "jboss-cli.sh --file=migrate-standalone-ha.cli"|, |as per migration instructions in Keycloak documentation. jboss-cli.sh complete without errors, and the 2.5.4 server started successfully. All operations seemed running fine, until I've tried to add another LDAP server to User Federation... When I click "https://%server_fqdn%/auth/admin/master/console/#/realms/%realm_name%/user-federation" link, I get "Resource not found" page, and server logs show this error: "ERROR [org.jboss.resteasy.resteasy_jaxrs.i18n] (default task-16) RESTEASY002010: Failed to execute: javax.ws.rs.NotFoundException: RESTEASY003210: Could not find resource for full path: https://%server_fqdn%/auth/admin/realms/%realm_name%/user-federation/providers" Also, Chrome console shows error with angluar.js <https://ibb.co/jzgDmF> Did anyone experienced similar problems? Any advice? -- <https://www.youtube.com/watch?v=coVJlV1LJ84>
