Finally I think found a solution which works after installing R 3.4.4 and RStudio 1.1.442 at my new Laptop and getting the same troubles.
What solved the problem was to create a Renviron file : file.edit("~/.Renviron")
and setting there a local path like this R_USER="C:/Users/my_name"
Now knitting with self_contained: yes is possible without error
The errors suppose not occur because that's human being and purposely use specific words...
For example: Error: pandoc document conversion failed with error 61 or Could not fetch...
Try running RStudio as administrator (right click icon, select run as admin, see above instructions)
Also see if the specific package that was unable to be reached can be moved to C: library.
By refer to above solution, try to run as admin but doesn't help, somebody take a look?

SOLVED: Dear @seankross, It knitted HTML but it broke.
When I changed my directory to local, it works perfectly.
I have used my project in Dropbox before.
That's same error which is socket 443 problem as well... The problem for me is that my local Linux same with RStudio.Cloud... Somebody take a look and discuss?
Believed that the socket 443 has love scammer concerns
