I'm attempting to upgrade a Cisco Aironet AIR-AP1832I-B-K9 from 8.3.143.0 to 8.5.140.0 via http using AIR-AP1830-K9-ME-8-5-140-0.zip. The firmware uploaded successfully, but the APs were unable to download the software and errored out. I've attached an image of the error. I've updated Cisco APs before and never run into this issue before. Any suggestions would be greatly appreciated.
