Gitlab geo secondary site clone url problem

I have followed all the steps to set up the primary and secondary geography nodes.
Everything was fine, and the synchronization project was normal, but I found that when I logged into the secondary site and wanted to git clone the project, the URL of the clone project on the secondary site was the same as the URL of the primary site. This seems a bit strange, Because I configured different external_url for primary site and secondary site.I checked every step and redeployed the entire geo process. But the result is still the same. Is this a normal and expected result?

The following is my site configuration information:
primary site and secondary gitlab version are both 15.4.6-ee(Omnibus)
primary site external_url is
secondary site external_url is:
