The “URI does not have hostname” error typically occurs when you are trying to use a Uniform Resource Identifier (URI) that does not include a hostname or contains an invalid hostname. A URI is a string of characters that identifies a resource on the internet.

Here are some common reasons why you might encounter this error and how to fix it:

  1. Missing or invalid hostname: Make sure that the URI contains a valid hostname. A hostname typically consists of a domain name followed by a top-level domain (TLD) extension, such as .com, .org, or .net. If the hostname is missing or invalid, you can add or correct it manually in the URI.
  2. Malformed URI: Check that the URI syntax is correct. Make sure that the URI includes the scheme, hostname, and path components in the correct order, separated by appropriate delimiters (e.g., colons and slashes). You can use an online URI validator to check if the URI is valid.
  3. Network connectivity issues: If the URI is correct but you are still getting the error, it could be due to network connectivity issues. Check that your internet connection is stable and that the hostname is reachable from your location.
  4. DNS resolution issues: If the hostname is correct but you are still getting the error, it could be due to DNS resolution issues. Check that the DNS server settings on your device are correct and that the hostname resolves to the correct IP address.

Overall, the “URI does not have hostname” error can be fixed by ensuring that the URI is correctly formatted and that the hostname is valid and reachable.
