Redirecting with Namecheap removes the path and sends all URLs to the home page

Question

I'm having trouble redirecting www to non-www links using Namecheap. I added a URL Redirect Record with a host of www and a value of http://example.com which works fine for the main (and mostly only page).

The problem is that I'm setting up SSL using Let's Encrypt and it needs to verify using the file served at www.example.com/.well-known/acme-challenge/whatever. But the way the redirect rule currently works is that I have it redirects every URL to http://example.com (the homepage) instead of just removing www from the current URL. This obviously breaks the Let's Encrypt setup since it can't verify that page using www since it redirects to the homepage instead.

If it matters I'm hosting this site on GitLab Pages so my other rule is an A Record with host @ and value 52.167.214.135. But seeing as my non-www URLs work fine I don't think this rule is causing an issue. Any ideas?

It is important to note that the value in the Destination URL affects where and how the URL is redirected.

Host: www1.example.net
Destination: http://example.com

Host: www2.example.net
Destination: http://example.com/

In the first case, www1.example.net will not pass values to the destination URL, so www1.example.com/xyz.html will redirect users to http://example.com only. Thus, all values that you put in the original URL under your domain name will be left out.

In the second case, www2.example.net/xyz.html will redirect users to http://example.com/xyz.html (pay attention to the symbol "/" in the configuration). All values that are put into the original URL under the domain name will be included in the destination address and applied in the results.

You have to add the trailing slash on the destination URL to get NameCheap to preserve URL paths.
