Transfer Aborted:Instance not found.

Hello. I'm writing here so maybe i will get some help. I'm getting this weird message Transfer Aborted:Instance not Found sometimes when i am accepting any pvp related join. Its happening a few times everyday. My internet connection is stable I've got Fiber Connection. My ISP is T-home Hungary. I don't know what is wrong. I'm posting here a Looking Glass so maybe you can help me how to fix it. Already tried to fix it with turning off the Optimize Network For Speed, it didn't help.I'm using two routers. The first is a router/modem provided by my ISP, the second is a Tenda N300 Router which is in static routing. Sort of a switch, but not exactly. Problem still persists. :

Hey!

Can you make sure that you have no proxy services running and have wiped the game UI: battle.net/support/article/resetting-the-world-of-warcraft-user-interface

The looking Glass report shows nothing that stands out too much. Could you tell me:
What troubleshooting steps have you taken? :
Details of issue : (i.e. what happens when the error occurs)
When does the issue occur? : (i.e. during the day, evening, etc.)
City and country :
Connection type :
(i.e. wired, wireless)

---------------------------------------------------------------------------------------
Only here for a while so let me know how I am getting on!

I have had a look over this and cannot see anything untoward going on here.

Can I get a DXDiag and MSInfo from you, these would need to be hosted on a site such as Pastebin and links given on the forum:
