Example request begins with Unauthorized OPTIONS request

[etnt]

Q&A (please complete the following information)

• OS: macOS
• Browser: Firefox
• Version: [e.g. 22]
• Method of installation: docker container (swaggerapi/swagger-ui:v5.12.0)

Content & configuration

How can we help?

When executing an example from the Swagger-UI, an unauthorized OPTIONS request is sent, which in my case is replied with a '401 Unauthorized'. So my question is if there is a way around this (I can't change my endpoint to allow Unauthorized request)?
