Linked to Yarn - There appears to be trouble with your network connection. Retrying
To circumvent the issue during the Oryx operations, you must create a configuration file that will specify a longer timeout when downloading packages.
At the time Oryx uses Yarn V1.22.15
Create a .yarnrc file at the project root
add network-timeout 240000 to the file
You can change 240000 to any value that is appropriate.
In case Oryx updates Yarn to 2.x, the file to be created will be named .yarnrc.yml and the value to append will be httpTimeout: 240000
