I'm checking our IAP 105s for a new image version using the web interface. We're currently on 6.4.2.6-4.1.1.11. When I go to the Maintenance link, select the Firmware tab and then click on Check for New Version, I'm getting the response 'no response received from server'; in some cases, I wait for it to re-set and try it again and I get 'image_check_operation-not-allowed'. And in still other cases, I'll wait again for a re-set, try it and get the message 'no new version available'. However, there are 6.4.3.x and 6.4.4.x versions showing up in 'Early Availability' on the software site.
There doesn't appear to be any problem of network connectivity because other outside servers are accessible. Anyone have any info on what this might be telling us?
