Do you still having this issue? I think you have a problem about your ip blocklisted by blockchain..
Try this steps for linux
Open your root or command promt and type
This code is to release ip's in your isp/laptop after that type
This code is to renew your ip then type
sudo /etc/init.d/nscd restart
This code is to clear your dns cache or flushdns just like in windows users..
And try to login again in blockchain.
I hope it helps...
will bookmark this whenever it happen again. thanks.
anyway, I already had loggedin to my account yesterday after hours and hours of waiting because they unbann them after 4 hours.
I don't have much to my blockchain wallet but still I wanna access this from time to time and just store few coins maybe less than $50.
