Unable to login to domain after extension updates

I have Joomla 3 running on my domain. I installed JConnect & Kunena extensions. Somewhere along the settings updates I was logged out and cannot reach the site. Chrome & Firefox both return the same error:

“…could not load the webpage because tcshoppe.bplaced.net took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection.
Go to bplaced.net/

Others, including admins can access the site. Is my IP blocked or what could be the issue here? Please help.

hello

your IP was blacklisted, please refrain from too many login attempts using wrong credentials.

ciao
