Also having same problem here.

Can you guys see if the browser version is working for your alternate accounts? I know Plarium is working on this issue right now. 

Browser Version Here 

Can't do  browser  version  on  iPad

Can't help with iPad, at least while things are being worked on, besides recommending to try a VPN and see if that lets you in on your alt accounts. 

Maybe Plarium don't wish to give Appreciation Packs to people with more than one account anymore.Any estimated time Plarium login will be operational again?

Sorry you're having this issue. Update: A VPN is working for many people. 

If you need a recommendation, Windscribe is free for several gigs of info per month. It is the one I use myself. Check it out in your app store.   

Please see the pinned post for more solutions. Good luck! Keep me posted there if you can. :)

Checked into VPNs I am not into spending the extra monies for that and I cannot see why we should have this inconvenience with your game.  You have programmers that should be able to fix this problem.  It is now going on 3 days and nothing.  Won't work on my phone either so its either fix this game which I have been playing and spending for 2 years now or I like others will just go to another new game with a company that can figure things out.  I would love to purchase this game with my company and surely turn it into an award winning game.  If Plarium is interested in selling I will send a proposal on their website.  Thank you for your time.
