Swagger JSON Format URL does not work using /v1/

Hello

Until today, when displaying the swagger file in json format we use a URL like this: https://MySwaggerhubServer.mydomain/v1/MyOrg/MySwagger/1.0.0

However, we are trying to install a new server, but this URL convention, does not work. 

So I found that this one will do the job:
https://MySwaggerhubServer.mydomain/apiproxy/registry/MyOrg/MySwagger/1.0.0

I wonder If we missed a proxy definition somewhere.

Does anyone already faced such kind of issue?

thank you
