Last Updated: | Applicable Hub Versions: 19.3 and later
When upgrading to 19.3 or later from a version earlier than 19.3.0.20190603, users must follow the steps below. If users do not follow these instructions, they may experience "Unable to connect to server" or "An unexpected error occurred" errors that prevent pages from loading, or be unable to log out of Hub.
These errors are caused by a large load on Keycloak (User Management). They are especially prevalent in the Chrome browser. If you are installing a new Hub instance on 19.3 or higher (rather than upgrading an existing instance), you will not need to follow the instructions below.
If you have altered Hub to use a keystore other than the default insecure keystore, you must also update Keycloak's standalone.xml
file to reference that secure keystore.
Note: If you are upgrading from a version that is also earlier than 19.2.1, please additionally follow instructions here.
