Site Is Down With Err_Connection_Timed_Out Error And Keeps Redirecting 301 To Itself

Our site went down without any new changes being deployed to it and we can't seem to figure out what happened.

The only error that we are seeing from debugging is that the website keeps redirecting 301 to itself(as attached)

Anyone had the same issue before? The webpage is not loading at all for us, please help.

Thank you.

Try temporarily disabling the seo addon. If it works, then I would check to see if mod_rewrite is installed and working.
