Hi @Eaven HUANG
Thanks for posting in our Q&A.
1, Please help upload full ccm.log and ccmsetup.log for our reference.
ccm.log(server): C:\Program\Microsoft Configuration Manager\Logs\ccm.log
ccmsetup.log(client): C:\Windows\CCM\Logs\ccmsetup.log
> It was confirmed that the client machine changed its default 443 port for remote control
2, To narrow down the problem, could you please let me know why you confirmed that the issue is caused by the client machine changed its default 443 port for remote control?
Thanks for your time.
Best regards
