Had to use a vpn to connect.
The Internet space most especially crypto forums have been bombarded with DDos attacks and admin gave no other choice then to increase the security verification to protect a total taken down of the sites.
Good thing is s that, with VPN you are good to go for the time being until everything goes back to normal again or better still DDos cool off a bit, previous discussion can be followed up on this issues to get the current update and suggestions from other forum members.
