Here they are… From two of the affected computers
To shed maybe a little more light of the problem…
Offline works as a charm, all “other online stuff” like “What’s new” is update as normal in the Launcher. The same goes for the Marketplace. But as I can’t sign in I have no use for them since they requier that…
I can sign in on the Answer Hub, Forums etc. from the sam computers without any trouble.
It occured after a dialogue that told me there were some updates to the launcher so I’ll restarted it from the dialouge and then it could not sign in anymore.
A hipshot guess… It feels like it’s trying to get updates but can’t get them and gets stuck in a endless loop that way… As it seeks for an updated version of the Launcher… As I said a wild shot 
Hi chaps,
We’re currently investigating a number of “Please Wait” issues, some users have reported that right-clicking and running the Launcher as admin fixes the problem, if you want to give that a try while we look into it further.
Edit: it may also be worth making sure this is an exception on your firewall too
xmpp-service-prod.ol.epicgames.com port 5222
Thanks
