I came across an interesting problem today while trying to subscribe to a podcast through iTunes where iTunes threw up an error (-9808) saying an unknown error had occurred.
I’ve used iTunes on this machine (Vista SP1) a fair bit and have had no issues with downloading podcasts before, however, I was logged in as a test user and wasn’t using my normal user account. Some quick checking found that it wasn’t our Internet Content Filter causing the problem, but did find this message in our ISA firewall log:
Failed Connection Attempt
Log type: Web Proxy (Forward)
Status: 995 The I/O operation has been aborted because of either a thread exit or an application request.
Destination: External (188.8.131.52:443)
Filter information: Req ID: 1b5d88f0; Compression: client=No, server=No, compress rate=0% decompress rate=0%
Searching for status 995 and ISA in Google didn’t bring up any useful results, but a search for iTunes and 9808 bought up a a heap of results. Turns out this is a reasonably common problem and found the solution at soccerislife8 and disabled Check for server certificate revocation in Internet Explorer.
After some more research it seems that updating to the latest version of iTunes won’t fix the problem?!
Checking Apple’s SSL Certificate in IE shows that its valid so its a still a mystery. I’m not impressed that I’ve had to disable security features in my browser for the sake of iTunes
