500 Server Error; cannot connect Battle.net account

I've been receiving 500 Server Error when trying to connect my Battle.net account to my SolidIce account for several days now. Is there a fix for this?

I can no longer manually add characters to SolidIce, so any progress on newer characters I've made continues unrecorded.

"One or more of your toons could not be retrieved from the WoW Armory."

I started having this error pop up after login a few days ago with no effect on my raffle ticket progress, but now my ticket progress is resolutely stuck at 96% despite having run a butt-ton ton of heroic dungeons between yesterday's login and today's. I tried deleting each of my linked toons and re-adding them, and it seems that Kaiza-Uldum-US is the problem toon. I saw from another thread (<- thread link) a while back that their problem had to do with recently-linked realms, but Uldum has been linked with Antonidas for months and this error only manifested within the last week. What can I do to fix this?
