When the front page is visited with a query string, the selected domain is not correctly identified in the hook_domain_request_alter hook. This leads to the default domain being selected. When used in combination with the Domain Config module to alter the front page, the wrong front page is loaded from config. When Domain Access is checked, a 403 is returned because the loaded page is not accessible from the requested domain.
1. Enable and configure Domain Access and Domain Config
2. Enable Domain Config for Basic site settings
3. Configure two country path domains: one default, one alternate
4. Configure Configuration > Basic site settings > Default front page with a node for the default country path domain
5. Configure the Default front page with a different node for the alternate country path domain
6. Navigate to the alternate country path domain with a query string added
7. Note the 403 forbidden error
The hook needs to be updated to remove the query string before setting the detected domain.

I'll be honest; this was a quick and dirty fix due to time constraints. If this doesn't seem like the right place to fix the issue, I'm happy to take another pass. I can confirm it fixes the issue for us though.
