Same. I've spent the last 20 minutes restarting the computer multiple times, making sure the internet is connecting properly, and re-validating the Tequila launcher (before anyone asks, I don't like the HC launcher because I could never figure out how to use it get multiple instances to run at the same time for 2nd account).
Not sure what is happening.
EDIT: I saw Rizlazz's reply while I was typing, apparently it's a known issue.
