2013 – “This item could not be crawled because the crawler could not connect to the repository.”

In the Error Breakdown in the Crawl Log – URL > Search Service Application, I am receiving an error for all SP sites I am attempting to Crawl

“This item could not be crawled because the crawler could not connect to the repository.”

I have already verified that the crawl account has access to the web applications and I am running SP 2013.

Thanks!
