Over the past few days, when entering Raid and Alliance Raid roulettes (it seems at random) i get disconnected with the error message 17:

This happens when the opening cutscene for the dungeon/raid would play and locks my character in that raid until they can kick me for AFK. The first major lockout was in Asphodelos 4, i queued with my partner and they made it in no problem and thankfully they managed to clear it with only a single healer. Once the raid was over i tried solo queuing for it and got the same issue, then damning another party to my fate.

The only solution i have seen for this is to reinstall the game, which at 74gb is a hefty ask. But i did it and Asphodelos 4 was then open to me.

I've tried doing the Alliance Raid roulette today and got exactly the same issue in what i can only imagine is one of the Crystal Tower raids from my login screen.

I really don't want to have to reinstall the game again as i know i'll get broadband throttled if i keep having to do it.

Does anyone have a less extreme solution?
