Resolving Constant Basic Auth Timeout Issues

I'm facing a persistent issue with a Basic Auth connection on my web application built on Classic ASP.

Key Requirements:
- Diagnose and fix the Basic Auth connection timeout issue.

Ideal Skills:
- Proficient in Classic ASP.
- Strong understanding of web application architecture.
- Experience with Basic Authentication protocols.
- Excellent problem-solving skills.

Code Below:

' Chamada
SET obj_http = Server.CreateObject("MSXML2.ServerXMLHTTP")

obj_http.open "post", urlws, False
obj_http.setRequestHeader "Content-Type", "application/json"
obj_http.setRequestHeader "Accept", "application/json"
obj_http.setRequestHeader "Authorization", "Basic" & Base64Encode( rTrim( "ABC" ) & ":" & rtrim( "123" ) )

obj_http.send json

sRetorno = obj_http.responseText

response.write( sRetorno & "<BR>" )
response.end

SET OBJFSO = Nothing
