IOS Remote Build ERROR

I’ve got some ERROR when I try remote build. I follow the official steps but thats no work.

It seems like SSH errors, but i do SSH with cygwin and it can connent to Mac.
So I have no idea how to figure it out.

I’ve resolved it myself. The issue is cause by giving the “.ssh” and “…/.ssh” directory in MacOS too much permission.
Use command chmod change the permission to 700 then resolved it.
Hope it can be useful for you guys who have the same issue.

and how does one change the chmod?
