Strange error when trying to add plugins

Hey guys,

I’m pretty new to WordPress so please be patient with my ignorance. I’ve set up a fresh install of the latest version last evening. There’s a plugin that I’d like to add, but whenever I go to the Add New section of the Plugins area, I get this weird message in the place where the plugins database should be:

You may also browse based on the most popular tags in the Plugin Directory:

An unexpected error occurred. Something may be wrong with www.remarpro.com or this server’s configuration. If you continue to have problems, please try the support forums.

I put up a screenshot here: https://69.167.236.42/WordpressError.png

I’ve Googled around but I haven’t found the answer yet. I’ve tried checking permissions, putting a fresh copy of all the wordpress files on the server, editing the hosts file of the server to include api.www.remarpro.com. Any ideas would be appreciated. Thanks in advance!
