SOLVED Supported WSUS version not found~

SCCM version: 1910 with KB4537079
server1: windows server 2019 + config mgr console
server2: windows server 2019 + sql server 2017(wsus db)
server3: windows server 2019 + wsus

I used server1 console to add SUP role to server3, but cannot work fine

WCM.log@server1:
