How to Fix Xeno Executor "Loading... | PID" Attach Issue
Are you experiencing issues where Xeno Executor gets stuck on [i] Loading... | PID: XXX with a yellow or red status dot and refuses to attach to your Roblox client? This is a common issue that prevents the executor from injecting into the game — and it doesn't affect everyone, which is exactly what makes it confusing. Fortunately, there's a quick, tested fix that resolves it in under a minute by adjusting your local network routing settings.
Why is Xeno stuck on "Loading..."?
When Xeno attempts to attach to Roblox, it sends background network requests to external repositories — Pastebin among them — to check for update routines and script dependencies before it finishes injecting. That's normal behavior for a lot of executors, not just Xeno.
The problem shows up when your Internet Service Provider, regional DNS, or a firewall blocks or delays connections to Pastebin instead of rejecting them outright. Rather than failing fast, the request just hangs — and because Xeno is waiting on that request to finish before it continues, the status stays stuck on [i] Loading... and never completes the attach. This is why some people hit this constantly and others never see it at all: it comes down to how your specific network path treats that one connection.
The fix works by adding a rule to your Windows hosts file that maps Pastebin's domains to 0.0.0.0. Instead of the connection hanging while it waits on a slow or blocked response, your system rejects it immediately — so Xeno skips past the stuck check and attaches right away.
Step-by-step: fix the Xeno attach bug
Open PowerShell as Administrator
Press the Windows key or click Start, type PowerShell, right-click Windows PowerShell and choose Run as administrator. Click Yes if Windows prompts you with a User Account Control (UAC) dialog.
Run the fix command
Copy the command below, paste it into the PowerShell window, and press Enter:
@("0.0.0.0 pastebin.com", "0.0.0.0 www.pastebin.com", "0.0.0.0 raw.pastebin.com") | Add-Content "$env:windir\System32\drivers\etc\hosts"; ipconfig /flushdnsThis appends three lines to your hosts file and flushes your DNS cache so the change takes effect immediately.
Relaunch Roblox and Xeno
Fully close both Roblox and Xeno Executor. Launch Roblox and join a game, then open Xeno and click Attach — the status should skip past the stuck loading state and attach successfully.

Fix FAQ
Xeno makes a background network request to Pastebin as part of its startup/update check when attaching. If your ISP, regional DNS, or a firewall blocks or delays that connection instead of failing it cleanly, the request hangs indefinitely and Xeno's status stays stuck on Loading instead of completing the attach.
Editing the hosts file to block a single domain is a standard, reversible Windows troubleshooting technique — it only affects how your PC resolves that domain locally. It does not modify Roblox, Xeno, or any other software. You can undo it at any time by removing the added lines from the hosts file.
You won't be able to view pastebin.com pages in your browser while the entry is in place, since your PC will treat the domain as unreachable. It has no effect on Roblox itself or on other executors that don't rely on Pastebin for their startup checks.
Confirm you ran PowerShell as Administrator (the hosts file write silently fails otherwise), that Roblox and Xeno were fully closed before retrying, and that you're on the current Xeno build from this site's download page. If it still hangs, the cause may be unrelated to Pastebin — check our Xeno FAQ or the Discord for further help.
