I'm having this same issue right now.

[robertmassaioli]

This issue seems to have fixed itself and I have not seen it since.

[omer-za]

This error happens to me now

[dougkeen]

This issue still exists due to coupling to search.maven.org, and the above issues correlated to outages of that service.
