Hi, We have seen this issue when we tried to bringup the UI on custom ingress path (default ingress path “/” works). Do you also have similar configuration? We tired setting spark.ui.proxyBase and spark.ui.reverseProxy but did not help.
As a workaround, we’re using ingress port (port on edge node) for now. There is option of using nodeport as well. That also works.
