This only happens to my toon in Shadowlands. I will get in then 30 seconds to maybe a few minutes, I’ll get DC’d. It will give me the streaming error message. After that I try to log back in to not even finish loading the toon before the same error happens. After I wait awhile, normally an hour or so, I try again just to have the above happen all over again. My other toons play just fine. It’d only on the one that went to Shadowlands.
