Start by reproducing the reported behavior on a Linux server with AnyProxy v4.0.6, comparing access through the server IP and through its domain name. The issue names no source file, test, configuration, or error log; done requires resolving the discrepancy between the expected and actual behavior and confirming interception works through the domain.
