Your server couldn’t connect to the resource (for whatever reason). It’s likely to be an intermittent issue on GitHub end. If not, the key terms to research would be:

  • “composer update failed to open stream + connection timed out”
  • “composer symphony/polyfill-php80 download failed”

Please, provide an update once you’ve solved your issue so that others may benefit from your knowledge.
