Help~After installing Exchange 2019, mail is stuck in Draft in OWA

Hi all

I dont undertand this symptom. 

Now I installed  one new DC, one new Exchange 2019(CU13) in active directory domain.

and I just set recieve connector(check anonymous user in Default Exchange) and created send connector

and I sent mail to my own mailbox(administrator), and I also sent mail to other mailboxes, but I only have stuck Draft folder in OWA.

before install Exchange 2019 CU13, I installed Exchange 2029 CU15 but it was same symptom so after removing Exchange 2019 CU15, I reinstalled Exchange CU 13. but it was same. 

DC and Exchange OS are Windows Server 2022 Standard on Dell H/W.

ipv4 192.168.10.202

subnet 255.255.255.0

GW 192.168.10.1

Dns1 192.168.10.201(DC)

It's the same as the link below, but there's nothing solved. T.T
