I have a collector that was working fine and now for the past 2 weeks when trying to upload it comes back with a 404 not Found Error. We are running 126.96.36.199 currently. I have ran packet captures and see the bidirectional traffic between my collector and the Cloud and do not see anything getting blocked. I have verified connectivity to the Upload URL and get the message back "It Works" from the website. I have rebuilt the collector from the ground up and re-certified it multiple times in the Portal. Yet no matter what I still get 404 and cannot find anything to indicate why.
