Upgrade HTTP client libraries.

The HTTP client library (gun-1.3) incorrectly appends a :portnumber suffix to the Host header for standard ports (http on port 80, https on port 443). This could cause compatibility issues with servers or gateways performing strict Host header checks (e.g., AWS Lambda, Alibaba Cloud HTTP gateways), leading to errors such as InvalidCustomDomain.NotFound or "The specified CustomDomain does not exist."
