Failed to connect the remote server

Hi everyone,
I followed the building constructions to build a new app using the latest master source code.
But it has a problem, I don’t know why?
And I also check the follow solutions, but no use. I am sure my config is 100% right/

  1. Stop battery saver if it’s active;
  2. Check your config;
  3. Wipe app data.

This indicates that native binaries weren’t built. Double check your build procedure.
