HttpError: DnsResolve issue

[Valkyrop (I_oL)]

Hey there,
So I’ve been trying to make a ’ live group members count’, and I somehow keep getting this error :

Code:

--Services
local Replicated = game:GetService("ReplicatedStorage")
local Storage = game:GetService("ServerStorage")
local Lighting = game:GetService("Lighting")
local Market = game:GetService("MarketplaceService")
local Space = game:GetService("Workspace")

local MainFolder = workspace:FindFirstChild("Game")
local School = MainFolder:FindFirstChild("School"):FindFirstChild("School")

local Http = game:GetService("HttpService")
local GroupID = 9854805

local function GetGroupMembers(ID)
	local Link = "http://www.roproxy.tk/My/Groups.aspx?gid="..ID
	local html = Http:GetAsync(Link, true) -- issue occurs here
	local pattern = [[<div id="MemberCount">Members: %d+</div>]]
	local size = tonumber(html:match(pattern):match("%d+"))
	School.Decoration.Announcements.GroupBoard.Info.Members.SurfaceGui.TextLabel.Text = size 
	print(size)
	return size
end

spawn(function()
	while task.wait() do
		GetGroupMembers(GroupID)
	end
end)

What does "HttpError: DnsResolve" mean?

I have this code, and it errors on the sixth line, where the PostAsync is. local _Http = game:GetService("HttpService") local Url = "https://www.rproxy.pw/groups/api/change-member-rank" local function DoPost(GroupId, NewRole, UserId) local Query = "groupId=" .. GroupId .. '&newRoleSetId=' .. NewRole .. '&targetUserId=' .. UserId local Response = _Http:PostAsync(Url, Query, 2) end

I’ve read that already, didn’t really help that much.

I think it basically means www.roproxy.tk doesnt exist, so you have to find another proxy server.

[Valkyrop (I_oL)]

Possibly yes, but sadly I am new to api and that topic [started today], so how would I find a new server?

I tried to use a diff proxy, returned me ‘doesnt exist’

Use the available group API endpoint instead, the ‘memberCount’ field is what you’re looking for.

[Valkyrop (I_oL)]

I tried, but it somehow returned to me ‘proxy is no longer available’

You can create your own proxy server with this:

Fixing HttpService: Make PUT, PATCH, DELETE requests, access response headers, proxy to any site, and more

ProxyService Roblox’s HttpService has always been severely lacking. This open-source project essentially aims to serve as a replacement, providing an Http client that opens the door to actually using REST APIs, reading response headers, reading status codes, accessing roblox.com from in-game, and more. Example uses are accessing Roblox, Discord, Trello, and Firebase APIs, including crazy stuff like logging into a Roblox account from in Roblox. You can use this for virtually any API. The way it…

Roblox Group Member Count to Discord

The following API endpoint can be used to fetch a group’s total member count. https://groups.roblox.com/docs#!/Groups/get_v1_groups_groupId This can then be dispatched to Discord through a webhook and displayed accordingly. Here’s a script I wrote which retrieves a group’s member count. local http = game:GetService("HttpService") local get = http.GetAsync local jsonDecode = http.JSONDecode local proxyUrl = "roproxy.com" --Change this to your proxy's domain. local baseUrl = "https://groups."…

Thank you! @Forummer and @realmile , appreicate it!
I will def dive deeper into the topic and examinate it further!

[Valkyrop (I_oL)]

By the way,
Is there an alternative way to replace the while loop with a sort of .Changed event for that proxy?

Because I always think that if I used too many while loops[ instead of .Changed etc], it’d take more memory and cause some issues

[Forummer]

Unfortunately not, I’d slow it down to once per 5/10 seconds or so (depending on how responsive you need the live count to be).

[Valkyrop (I_oL)]

Oh.
Yeah the delay doesnt matter for me here, so I could set it to 0.5 or 1 if needed.

[Forummer]

Roblox provides an allowance of 500 HttpService requests per minute, a frequency of every 0.5 seconds would consume 120 (roughly a quarter) of those requests, which is fine but should be noted.

[Valkyrop (I_oL)]

Oh. Thanks for that important note,

So if I wanted to have 10 proxy calls, would it cause issues?( performance or wont work properly)
