This tool addresses a specific technical error that occurs when a server is accessed by its IP address instead of its configured domain name, resulting in a blocked request. It is for website administrators, developers, or anyone managing a web server who encounters this hostname configuration issue.

• Error Diagnosis: Clearly identifies the 'Invalid hostname' problem, explaining that the server is rejecting requests made directly to its IP address.
• Log Inspection Guidance: Provides direct instructions for checking server error logs to find more detailed information about the failed request, which is crucial for troubleshooting.
• Configuration Solution: Focuses on the core fix: updating the server or application configuration to recognize and accept the correct domain name, moving away from the blocked IP address.
• Access Restoration: The primary outcome is restoring normal access to the server or website by implementing the proper domain-based configuration, resolving the blockage.
