Roblox applications refuse to open on Windows

Nope. It was fixed about two to three hours later after posting this bug report.

I’m having the same issue as well

I had this exact same issue but on Mac a while ago.

As of now, I am also receiving this error. I was able to play games normally earlier today, so this bug is recent. I don’t want to jump to conclusions, however was the fix that was made earlier with the site being partially down have something to do with this?

I can now confirm this is happening to me too on Windows. Studio refuses to launch with the exact same error.

I’m having the same issue, I can’t even uninstall roblox or roblox studio without getting this error. Restarting my PC doesn’t fix it either.

I have been having the same exact issue, I started having this issue on 2021-06-23 at 12:30 PM (est). I know for a fact this is an API. This issue is one of the ones that come and go, I had it happen to me 2 times and after a couple minutes it goes away, and then in a day or so it comes back.

Studio is back up for me.

I’ve also been having the same issue with launching both Roblox and Roblox studio. This happened to me on 6/24/2021 at around 6:25 PM EST. The error that kept on popping up when I try to launch the Roblox launcher went away in ~20 minutes, however my Roblox studio is still experiencing the same issue when I attempt to launch it.

Edit: My Roblox studio now works after reinstalling it.

I’ve had a similar issue occur to me as well. For anyone else still encountering this, a temporary solution that I’ve found was to disconnect & reconnect to your internet connection. Not sure if it works only for me but it’s still worth a shot.

To everyone above - your reports don’t seem to be part of what has happened to me. Please make a new report instead of plopping unrelated information into here and complicating the situation for the engineers.

Sorry, to hijack your issue @ItsKoiske .

For those who are having the error “An error occurred while starting Roblox Details: HttpSendRequest failed” etc. Can you run the following from a command prompt?

nslookup clientsettingscdn.roblox.com

It should give you back output like

Also, can you check if you also get an error when just navigating your browser to https://clientsettingscdn.roblox.com ? The expected output should be just the JSON.

{ “message”: “OK” }

If you do get an error, sending back a screenshot of it would be helpful. You can DM me if you’d prefer for this or the output for the above nslookup command.

Hello, this is what happened to me when I clicked that link.

Though, when I just ran it anyways despite the warning, I did get that JSON message.

However, when I clicked the first link you sent clientsettingscdn.roblox.com I got that JSON. I also ran the command and got the output that you sent.

So now I can join games and my roblox works properly. If this command was meant to fix it, thank you very much! I’m not sure if it was because of the command or if I got lucky, but hey at least it works now.

I have been experiencing this issue as well. The issue goes away and comes back periodically.

@t1dtony and @CeaseHerSalad if you can also send back the output of the nslookup command above, it would be very helpful in debugging this issue (you can DM me the result if you prefer).

Thanks everyone who sent debugging info. Our CDN provider says they found the issue and have fixed it.

If you are still seeing this issue, please reply again and DM me nslookup results so I can dig into it further.
