I recently upgraded Monitor server to 2023.3.1, and since then I've been getting alerts for "Connectivity - arcgis_server_discover (%)" for our federated servers. If I try to reconnect, I get the error "Undefined is not a function." See screenshot below. I don't see anything in the logs for Portal or either of the affected servers. I also upgraded Enterprise from 11.0 to 11.1 a few days later, but that did not seem to improve the situation.
Has anyone else encountered this, or have any thoughts on how to proceed?
