On Kiali 1.24.3 on s390x architecture cannot stay logged into kiali console.
After login, I can see the kiali console page for less than a second then,
    UI error msg: "Your session has expired or was terminated in another window."
    Kiali pod log error: "authentication.go:318] Token is invalid: token contains an invalid number of segments"
 
 Tried by multiple users on multiple browsers, all faced similiar issue. Note that the openshift, and jaeger authenticate fine and do not show similiar issues.

Issue does not appear on ppc64le architecture using the same version.
