can't svn checkout after re-creating svn repository

I've just deleted and re-created a Subversion repository (a Subversion app named "svn"). It's set up with the same parameters as the previous one. Unfortunately, when I try to do an svn checkout from my new repository (URL: https://svn.mydomain.com/), I get:

1

Error: Repository moved permanently to 'http://svn.mydomain.com/';

Note the http, not https. This is happening even though I have https enabled on the website that is tied to my new svn application. And if I try to access http://svn.mydomain.com/ I get:

1
2

Error: Server sent unexpected return value (405 Not Allowed) in response to OPTIONS   
Error: request for 'http://svn.mydomain.com/'

I've tried deleting and re-creating the site using the control panel, again associating it with the new "svn" app, but it still doesn't work. It seems to me like something behind the scenes isn't working, as if there might be some remnants of the old config lingering that the control panel didn't clean up when I deleted and re-created the svn app and the site that ties to it.

Is this something I can fix?
