What happend? I can't sign in visual studio after I sign out! I restarted visual studio and even restarted my computer, but nothing changed at all!

Off the top of my head it looks like there is something blocking Visual Studio from communicating with the remote resource. It could be intermittent or it could be a problem with your network. You're running the community edition so I'm assuming you are not working at a company where you can have someone else test their connection. Things that come to mind: Ensure you are running the latest update of VS. Temporarily disable the firewall and see if it works. Create a new user profile in Windows and try to run Visual Studio with your existing MS account. If it works then the issue is with your profile otherwise it is machine level. Run VS in safemode ( /safemode ) and see if the problem goes away. If it does then there might be an extension causing problems. Run VS with logging ( /log ) and then check the generated activity log to see what it says. Use VS's Report a Problem to report the issue to MS. That will collect the necessary information to send to them to look at.

Hi @水知, Welcome to Microsoft Q&A! Have you tried to sign in to VS with another account? Please try the following steps: Close all running VS instances. Update VS2022 to the latest version with Visual Studio Installer. Delete your browser history, cache and cookies. Delete all files of %localappdata%\.Identityservice . Relaunch Visual Studio and sign in account. Sincerely, Anna If the answer is the right solution, please click " Accept Answer " and kindly upvote it.

Run VS in safemode (/safemode) and see if the problem goes away. If it does then there might be an extension causing problems.

Run VS with logging (/log) and then check the generated activity log to see what it says.

Thanks but the problem is not solved...

My VS is latest, and I disabled the firewall.

I think my machine not have any problem since I could login VS last year.

The other user profile dosen't help...

I don't know how run VS in safemode, I'm using blend for Visual Studio...

I found a new problem that when I use system browser to login, after I submit the account and password, I'll be redirected to visualstudio.microsoft.com, which is really annoying...

What happened when you used a different user profile? If you were able to authenticate in VS then the problem is with your main user profile in which case you need to clean things up. If it didn't work then the issue is with VS.

Run VS in safemode by going starting the Developer Command Prompt (from the start menu) and then typing devenv /safemode /log <logfilepath>. Replicate the problem and then go to the file <logfilepath> that you specified and get the logs.

I don't know what you mean by "system browser". I also don't understand what you mean by "submit the account and password" and being redirected. VS login isn't related to your browser logins for MS, although you may be using the same MS account.

Have you check the Event Log for Windows to see if it generated any messages?

Thank you but still not solved yet!

I tried another user profile but nothing different.

There's 3 ways to login visual studio:

Embedded web browser

System web browser(That's the "system browser" I meant)

Windows authentication broker I've tried all of them but no one is usable. When I tried to sign in the embedded web browser: (The failure reason changed today but I still don't know how to solve it, Seems my visual studio can't connect to network?) When I tried to sign in with system web browser(It's a option that could be found in the "Account options" below the "Sign in" button): First I changed my Sign-in options "Add and reauthenticate accounts using" into System web browser(I only changed it). Then I pressed "OK" and next "Sign in". And the browser opened and ask me to choose an account to Sign in: And then I choose my account and inputted the password and submitted. Then I'll be re-directed to localhost(not happened before today) or visualstudio.microsoft.com(The situation of image 1 haven't occurred before): Image 1: Image 2: Then I tried to use Windows authentication broker and It's not usable like embedded web browser. After I tried to run VS in safemode, there's no "Sign in" button. I don't know where to get <logfilepath>, if I type it directly I'll be told "syntax of the command is incorrect."

I've had issues with the embedded version before. The localhost is a known issue that I ultimately got closed as won't fix. I'm not sure about the SSL error. It initially makes we wonder about whether you've changed your SSL settings such that it doesn't work anymore but that would be odd.

Are you able to log into your MS account using the regular browser, say to DevOps, Outlook or Office?

I've had problems in the past getting the browser to pass back the token once authentication is successful in some cases. But in those cases the initial authentication screen provided an option to use a device code instead. See if you have that option. If so then use the device code. It'll open the browser window and ask for the code. Then you are authenticated. Not sure if that works here though.

I've tried Outlook and Office and I signed out and signed up again, they can run properly. Plus, before I wrote this comment I was coding using Github Desktop, then when I pressed "push", I found even my Github Desktop can't connect to the Internet. Then I searched for solutions and then found my Internet Properties>Use SSL3.0 is off. I enabled it and Github Desktop is usable now, then I tried to add account to VS and I successfully added it(Not successfully signed up), but my MS account still can't sign up, still "could not establish SSL connection"

I'm confused now. Originally you said you couldn't add the account. That is what the screenshots show. But now you're saying you were able to successfully add the account but can't "sign up". Please provide updated screenshots.

The more I contemplate your issue the more I wonder about Blend. Blend has minimal support from VS these days. TBH I don't even know how you got it. Under the hood it is still VS 2022 but I don't have any way of knowing whether it installed all the necessary components (and updates) needed to work with the changes that occur with the identity system. I'm therefore going to recommend that you download a full copy of VS 2022 Community and install it. Once you have it installed then sign in. If it works then I'm going to recommend you use it instead of Blend.

I'm also confused...

Originally you said you couldn't add the account

Yeah that time I can't sign up due to the error.

But now you're saying you were able to successfully add the account but can't "sign up".

Then I reinstalled VS for 2 times, and I can "add" the account, that means my account will appear below the "All Accounts" title but the "Sign in" still ramains(sorry I can't show you due to I reinstalled VS again and now I can't even "add" my account). that seemed means I'm not signed in yet.(The "Sign in" button at the top right corner is still "Sign in" rather than my account too) And sorry I made some mistakes. All my "sign up" above means "sign in"!

TBH I don't even know how you got it.

I choosed UWP when I install VS, then Blend will be also installed.

Under the hood it is still VS 2022 but I don't have any way of knowing whether it installed all the necessary components (and updates) needed to work with the changes that occur with the identity system

Blend for VS can work as well as VS, before the problem occured, I was using Blend for VS all the time for years! Until... I added my Github account here:

Then I signed out my account and tried to add another account. Then... It's what you see here.

I'm therefore going to recommend that you download a full copy of VS 2022 Community and install it. Once you have it installed then sign in. If it works then I'm going to recommend you use it instead of Blend.

I tired just now and now it's what it likes:

VS, not Blend... I'm thinking about using System Restore, is that useful?

System restore isn't useful here.

Please confirm you have enabled TLS 1.2 on your machine. MS has provided this test script to confirm it is working.

Invoke-WebRequest -Uri status.dev.azure.com -UseBasicParsing).StatusDescription

Hmm... I can't run your script

Plus, I've already enabled TLS at inetcpl.cpl

So it's really strange...

Michael Taylor 53,496 Reputation points

Sorry, the script is missing a starting paren. Try this.

(Invoke-WebRequest -Uri status.dev.azure.com -UseBasicParsing).StatusDescription

There is more to SSL than just the protocol. The above script also confirms you have the appropriate encryption algorithms enabled. If you don't then handshaking will fail.

At this point I've run out of ideas. Your system seems configured for the modern SSL requirements and it seems to work partially. Outside what Anna recommended around deleting your cached identity settings I don't know what else to do here. If Anna's suggestions don't work then you might need to submit a support ticket to MS using Report a Problem and see if they can take a closer look at your specific scenario.

It's embarrassing... I want to submit the problem but I can't.

Finally I found that the problem is caused by the network environment... Out web here is aiways odd...
