The bug

When querying the API for specific data, including an extra slash after the server hostname returns a 405 error.

What I expected to happen

The request should be resolved successfully.

Steps to reproduce

1. Make a request to the API of an Octopus Server for a specific resource:
   'https://octopus-server/api/Spaces-1/projects/Project-1'

2. Add an extra slash after the hostname of the server:
   'https://octopus-server//api/Spaces-1/projects/Project-1'

Screen capture

Affected versions

Octopus Server: 2021.1.7595
Issue was not present in 2021.1.7500

Workarounds

If the name of the resource is known, you can use partialName=NAME to have the request succeed however this may cause different issues.
