Unexplained 301 redirect preventing google from crawling my site

Hi,

I recently used the “fetch as google” google web master tools resource just for checking and was very surprised to see that it could not crawl my pages because of a 301 redirect that I had never implemented and that created an infinite loop. As a consequence google can’t see the content of my page, which is not very good for ranking.

If I change, in wordpress settings, the url from https://www toward https://, I don’t get the infinite loop 301, but a 301 from https:// toward https://www. It makes the content non readable as well.

Has anyone an idea of what going on ?
