CI: Sauce Connect randomly fails so try twice
Browse files Browse the repository at this point in the history 
Twice now I've seen Sauce Connect fail with the unhelpful message:

    Error: failed to bring up tunnel VM.

Both of which succeeded on a rebuild without changing anything.

Well, that didn't work, I'm getting that error message again but it doesn't try to reconnect: https://265-598343-gh.circle-artifacts.com/0/tmp/circle-artifacts.maPmtm4/sauce-connect.log

Presumably this means that when it fails, it still exits with a successful non-zero exit status. Instead, lets check for the readyfile: 6f0c2f2

Fun fact, it also deletes the readyfile when it exits: 6dad20c
