I access My Task node in Main Scene Like below.

sub init()
   m.Response = CreateObject("roSGNode", "TaskNodeFile")
   m.Response.control = "RUN"
end sub

And Task node Code Like below.

sub init()
   ?"init() - Start"
   readdata = CreateObject("roUrlTransfer")

   data = "http://Domain:Port" 
   readdata.setUrl(data)

   readdata.SetMinimumTransferRate(1, 75)

   ? "data is " data
   m.port = CreateObject("roMessagePort")
   readdata.setport(m.port)
   readdata.gettostring()
   readdata.SetRequest("POST")

   request = readdata.AsyncPostFromString(data) 
   ?"request : " request
   while (true)
      msg = Wait(3000, m.port) 'Here It's Crashed. I also tried with the 0 MilliSecond. " It's Give a Execution Time Out 
      statusCode = msg.GetResponseCode() 
      if (Type(msg) = "roUrlEvent")
         statusCode = msg.GetResponseCode()
         headers = msg.GetResponseHeaders()
         if msg.getresponsecode() = 200 then
            Response = msg.getstring()
            headers = msg.getresponseheadersarray()
            ?"Response : " Response
            exit while
         else
            m.top.isError = "true"
            m.readdata.asynccancel()
            exit while
         end if
      else
         ? "wait for data"
      end if
      end while
end sub

Here the issue is: I tested this Code with 2 Roku premiere+ devices.

In 1st Device Internet Speed: 10mbps and
In 2nd Device Internet Speed: 50mbps.

I checked My API Response using the Postman tool :
With 10mbps: It takes an 1800 MilliSeconds
With 50mbps: It takes a 350 MilliSeconds

In My Case With 10 Mbps, The Application crashed with this line msg = Wait(3000, m.port). Here, I also tried with the 0 MilliSeconds. After also It's Crashed and Gives Execution Timeout. If Some Internet issues, It's no waiting. It's Directly Crashed. Does anyone Found Good solutions or How to handle this Scenario?.

First off, your task is not set up correctly

sub init()
    m.top.functionName = "codeToRun" 'what will be called on task.control ="RUN"
end sub
function codeToRun()
    'do stuff here
end function

  as you have it the task will do stuff only when created of task.control ="init"

since this is in a task and should be running on a no blocking thread try 

msg = Wait(1, m.port)

 otherwise you are waiting 3000 milliseconds each loop

I already tried which you suggest. My Task node like below : 

sub init()
    ?"Start - init()"
    m.top.functionName = "MakePostRequest" 'Roku execution skips this line in my case.
    ?"End - init()"
end sub

function MakePostRequest() 
    ?"Start - MakePostRequest"  'The call doesn't come here

   readdata = CreateObject("roUrlTransfer")
   data = "http://Domain:Port" 
   readdata.setUrl(data)

   readdata.SetMinimumTransferRate(1, 75)

   ? "data is " data
   m.port = CreateObject("roMessagePort")
   readdata.setport(m.port)
   readdata.gettostring()
   readdata.SetRequest("POST")

   request = readdata.AsyncPostFromString(data) 
   ?"request : " request
   while (true)
      msg = Wait(0, m.port) 
      statusCode = msg.GetResponseCode() 
      if (Type(msg) = "roUrlEvent")
         statusCode = msg.GetResponseCode()
         headers = msg.GetResponseHeaders()
         if msg.getresponsecode() = 200 then
            Response = msg.getstring()
            headers = msg.getresponseheadersarray()
            ?"Response : " Response
            exit while
         else
            m.top.isError = "true"
            m.readdata.asynccancel()
            exit while
         end if
      else
         ? "wait for data"
      end if
      end while
      ?"End - MakePostRequest"
end function  

I make a separate project for this but here also result is the same.

I have to do is stand there until there is a response. Because I created multiple Task nodes and every task node Depends on Each Other. Currently, your ways are happening like => Consider I used 3 Task node. so First It's 2nd Task node Response comes. After 3rd Task node Response comes then it's Run 1st Task node Response comes. But I need to run 1st, 2nd, 3rd wise.

Are you sure that your "task" xml extends task? not sure why it would skip that line. "functionName" is the field that is called as a function when you "run" a task. 

https://developer.roku.com/docs/references/scenegraph/control-nodes/task.md

since this is a task and not blocking, omit the while loop and don't do async

  urlhost = CreateObject("roUrlTransfer")
    urlhost.SetCertificatesFile("common:/certs/ca-bundle.crt")
    urlhost.AddHeader("X-Roku-Reserved-Dev-Id", "")
    urlhost.InitClientCertificates()
    urlhost.SetUrl(m.top.url)
    rsp = urlhost.GetToString()
    
    ResponseJSON = ParseJSON(rsp)
