github.dev stuck on "Setting up your web editor"

[Errorbot1122]

For some reason github.dev gets stuck on the "Setting up" screen indefinitely.

I'm not sure why, but I think it may have to do with a problem with vscode.dev.

I'm not sure if this is a bug or something else, but if you need to know, I can send you my system specs, just ask!

BTY: I'm using a Chromebook, and I currently do not have codespaces, I just think that this is the most relevant category for this problem.

[KevinMSampson]

I'm having the same issue on multiple browsers across mac & windows.
Looks like the Content Security Policy is blocking some new directives from different vscode urls

[KevinMSampson]

This isn't specific to Codespaces, I'm using GitHub.dev (browser-only client-side vs code)

[ia-mfriegang]

Yeah I just realized that :/ same issue still here. Are you in a corporate environment? I have a feeling its some security policy somewhere

[KevinMSampson]

That I am 👍🏼
I did get past this screen by having our networking team troubleshoot and add some urls to the whitelist.
It doesn't help that all the GitHub whitelist IPs in their docs are IP-specific instead of domain

[ia-mfriegang]

just confirmed it was the same issue on my end. Its working as expected now

Tell me Sir how you passed that page.
Mine is just stucked there.

[jfullstackdev]

never experienced that on Chrome, I even use Codespaces which is heavier than that

maybe low memory, browser extension, browser itself, firewall, antivirus local setup

[krishkumarsingh1545]

Oh Whatever I fixed it.
The problem was the certificate was expired so I updated it manually

[adityawisecoder]

I also encountered the same problem, but I was able to resolve it by enabling my VPN and accessing the web-editor, which appeared to be working fine. Once I disabled my VPN, the issue was resolved and everything returned to normal.

Hopefully, this solution will work for you too!✌️

[krishkumarsingh1545]

My SSL Certificate was expired.
So I updated it with a new one.
That worked for me and never had that problem again.
I think using a VPN might modified your certificates too or something like that.
By the way, thanks for the help.

[rhoitjadhav]

Not sure how, but enabling VPN has magically worked.

[tajamulkhann]

The best solution is to Connect to a VPN. The issue will be resolved 100%

Hi I'm having the same issue with multliple browsers:

• Safari Version 18.1 (19619.2.8.111.5, 19619)
• Chrome Beta 132.0.6834.15
• Chrome Stable 131.0.6778.86

All in Mac 14.7.1 (23H222) with M1

Tried with my work vpn and without it, I cannot use other vpn. Also I'm seeing the same issue with other coworkers

[krishkumarsingh1545]

So, My SSL Certificate was expired.
So I updated it with a new one.
That worked for me and never had that problem again.

Try to look if any certificate file is expired and update it.

[pablitok]

Didn't have luck with a vpn but now it's working without any change

I downloaded the latest version of Git and that worked for me, hope it works for you as well.

[sriA-97]

try updating the git to the latest version in your local machine.

[shiva-srivastav]

I also face same issue.

[Debjyoti30]

I am also facing the same issue. Please do share the drill if this issue has been resolved for you.

[sriA-97]

try updating the git to the latest version in your local machine.

[Debjyoti30]

It started working just today without any changes being made. It might be related to quotas, but I am not aware of the specifics.

[shiva-srivastav]

now its working.

Facing this issue

[tscpiece]

I couldn't connect to github.dev (codespace) or vscode.dev on my home network, even after clearing cookies and turning off the extensions.
I could ssh into it by gh cs ssh with no issues.
Then I connected to a VPN and now the website's working.

[Stan370]

This is a known bug with github.dev (the VS Code web editor) — it can get stuck forever on “Setting up your web editor” when “Direct Mode” (the browser-based VS Code runtime) fails to initialize properly.
it’s often caused by cached state, service worker corruption, or network/extension conflicts.

github.dev can open in two ways:

• Direct Mode (default) → VS Code runs entirely in browser, using IndexedDB and web containers.
• Server Mode (via vscode.dev proxy) → VS Code runs on Microsoft’s cloud backend and syncs via websocket.

if Direct Mode breaks, you’ll see that “Setting up your web editor…” message forever.

---

open Chrome devtools on github.dev:

Ctrl+Shift+I (Windows/Linux)
Cmd+Option+I (Mac)

then:

Application → Service Workers → Unregister
and clear:

Application → Clear storage → "Clear site data"

then reload:

https://github.dev/<user>/<repo>

---

or force disable Direct Mode via localStorage

[Darginec05]

same issue in every browser

[krishkumarsingh1545]

yeah changing browser won't fix the issue, you have to download the updated version of expired SSL certificate or just try any VPN

[Ninad7n]

This fixed the issue for me
Network → Wi-Fi → DNS
8.8.8.8
8.8.4.4

[ShaileshParmar11]

I worked for me

[DevZ44d]

I also encountered the same problem, but I was able to resolve it by enabling my VPN and accessing the web-editor, which appeared to be working fine. Once I disabled my VPN, the issue was resolved and everything returned to normal.

Hopefully, this solution will work for you too!

If GitHub.dev is stuck on “Setting up your web editor,” try these simple steps: use a modern browser, disable interfering extensions, clear your cache, and reload. Logging out and back in or opening a smaller repo can also help. Check your internet connection and GitHub’s status page. These usually fix the problem quickly and you can use also this vpn to solve your issu kalkulator
