problem in blog section

ok, I have a static page that loads, and I set another static page for the “posts page” under the general>>reading section.

That loads the blog posts onto the page just fine, but now when you click on the comments link, it comes to a error page.

https://www.derekswitzer.net/dereks-blog
and the link that it takes you to when you click the “no comments” link is: https://www.derekswitzer.net/http:/www.derekswitzer.net/?this-is-a-test-post#respond.

Any idea why it is adding my domain name again? And what file in wordpress can be altered to fix this?? Thanks a lot, I don’t want to start posting blog content until I make sure things are working ok…
