Issue with Swagger UI Endpoint Access via FQDN vs. IP Address

[sacredabhishek]

When utilizing Swagger UI for the API with a Fully Qualified Domain Name (FQDN), an error occurs for the endpoint. However, the same endpoints function correctly when accessed via IP. What could be the potential reason for this issue?

The backend technology stack consists of Python and Django.

The error message received is:

Failed to fetch.
Possible Reasons:
- CORS (Cross-Origin Resource Sharing) issue
- Network Failure
- URL scheme must be "http" or "https" for CORS request.
