Constant Error 90002 and 2002

[Trool323]

I have connected and completely reset the router to the day it was bought and set everything anew
I have also updated any drivers regarding the internet and overall parts of the PC
I am directly connected to the router,as well as i can connect directly into the Ethernet cable and bypass the router

I have tried both and it seems like the router doesn;t have to do anything with the connection problems
I also called ISP and asked them if they had some problems or if they added few blockages here and there onto our line (They responded that there were no changes and they went to check if everything is fine,and it was fine)

I kindly asked my friend if he could log onto my account to just check if the problem has to do something with the account
And he was able to freely log onto it after the error 90002 (moments before he logged on i tried to log on myself sevral of times)

I tried few things to fix the problem
Even updated the system (I am using Windows 10 Pro)

I forgot to mention,I don;t get any queue while loging into the Server (Light/Lich)
I wait around 30 sec and then get Error 10150 (Maintenance error) and when i try to log back onto the server i get 2002
