Problem Solved ^0^
It is an user error.
From my Mac's Ekos profile, I unchecked "INDI Web Manager" and everything works.
If I have it checked, I guess, INDI Web Manager throw an IntegrityError because I am trying to save the same profile name again.
If I have different profile name between INDI Web Manager and on Ekos (Mac notebook side), it does not work either and I have no idea why.
But, it works now.
Thank you everyone for your help.
Thanks.
Jeff.
