Sandbox fails to complete initialization on testnet -- it doesn't even try to "fast-catchup." Can anybody help?

  • What is your OS? (Ubuntu/macOS/Windows? version? if Windows how do you run things?)
  • What is your Docker version? Have you tried to reset Docker to factory defaults?
  • What is your sandbox version? git status and git rev-parse HEAD
  • Can you provide the full output of ./sandbox up testnet and the full sandbox.log (you may want to upload it on https://gist.github.com/ and link it there)?
