WARNING B2_CALL Failed to send request

#1

Now that I have B2 authorization sorted (thank for that in the other thread) I see this warning now in the console logs. Is this something to be concerned with?

This is normal with B2. Their upload servers are designed to return a number of different errors (see https://www.backblaze.com/b2/docs/integration_checklist.html) and every B2 client is required to handle these errors gracefully.
