Hi getting a 'streaming error'

i entred stratholme (service entrance for undead) with the group nd went through the instance doorway - I was ejected from game - on relog it come with
streaming error wow 51900322
I have now tried about 5 times to log in and every time its the same …!

Just restarted comp etc etc - and even reset my modem … but still it wont let me in
we were being ganked as i stepped through the instance portal.

Its now 23.13 UK time and its still not allowing me to log in - same error. I think my character is somehow stuck in the instance portal please devs can you reposition my char?

I’ve just reinstalled the wow classic and ITS STILL not letting me in highlighting the same error…! I belive the gankers were upto far more than just ganking …! If I lose this Char wow Devs I will not lvl another one - nor any further subs will ensue…!

I had another low lvl char on era not aniversary servers and it let me log in no problem so its definitely something to do with the anniversary servers. I find it really strange that we were being ganked at the time of it happenning and cant help but feel that those doing it were upto something far more nefarious. I think my char has got STUCK somehow as I entered the instance door to strat undead (service area). maybe the Wednesday reset will free it i will wait to see, if a Dev can look into it i would be grateful as I have spent alot of time getting this priest char to lvl 60.
Merry Christamas everyone.

I fixed it … after trolling through the internet it so happens this error has occurred quite often to other people whom were as frustrated about it as i was.
SOLUTION
Delete and/or SHRED (I shredded) using your anti viral every morsal of wow and bnet from your computer. The hypothesis is that retail shares some of the files with classic. After re-installing bnet I ONLY reinstalled wow classic and it has worked seemingly yet to go back into stratholme where the error was but at least im able to log back into wow.
All Good.
