Hi, it seems that the attached error has nothing to do with Syncope nor with HA.
A quick search for websocket HTTP upgrade is not supported by this protocol e.g. the attached error message, brings to: https://stackoverflow.com/questions/30667429/websockets-through-apache-and-tomcat-http-upgrade-is-not-supported-by-the-ajp-p It seems you need to configure properly the web proxy sitting in front of the Console component(s) to support websockets.

Hi, we are currently configuring syncope in our test environment. In this environment there are two servers each running tomcat 9. Each of the tomcats has core and console deployed. These installations share a common Database in a separate Mariadb cluster. In core.properties of each node the following line is configured as shown in the HA-Section of the documentation [1]: ”persistence.remoteCommitProvider=tcp(Addresses=<ip of other node>,TransmitPersistedObjectIds=true)”. Tcpdump shows that packages are coming in on the other node when logging in and out. Logging in works on both nodes and we can work like this. There is an external hardware-LB with both of the nodes configured as backend Servers. Logging in via the LB works initially. After some requests I am logged out with the error message “Session expired: please login again”. In the core.log file I can see the attached exception. Is there something I am missing in regards of the clustered operation of console or core?
