"Connection to server lost. Quit the app and log in again." issue

So I’ve been mentioned just yesterday about warcraftlogs. I want to use it to improve my way of doing things, but as I try to upload my log, I get the error “Connection to server lost. Quit the app and log in again.”. I may have done the relog thing about 60 times now. No answers found anywhere. Also asked a question on another thread where someone else seems to have the same problem but only a question as a reply is present. No further information that mentions if it was fixed or not. I require assistance please.

This happens if you have set up Windows networking to not allow cookies to be set.

I will have to look into that. But if you do know how, can you explain to me how to do it?
