  • This error is not caused by your ABP solution/services directly. ABP Studio can’t complete login because it can’t reach the OpenId Connect discovery endpoint (https://account.abp.io/.well-known/openid-configuration).
    The message “No such service is known … (account.abp.io:443)” indicates a DNS/network resolution problem on the machine (or corporate network/proxy), not an ABP Studio credential issue.

  • Fix steps (apply in order):

    1. Verify DNS resolution

       • From the same machine, run:
         • nslookup account.abp.io
         • ping account.abp.io (ICMP may be blocked; DNS result is what matters)
       • If nslookup fails or returns an internal/blocked address, fix your DNS (corporate DNS, VPN DNS, etc.).

    2. Check proxy / firewall / SSL inspection

       • If you are behind a corporate proxy, ensure account.abp.io:443 is allowed and that the proxy is correctly configured for Windows (WinHTTP) and the current user.
       • If SSL inspection is enabled, ensure it does not break TLS to account.abp.io.

    3. Allowlist required domains

       • Allow outbound HTTPS to at least:
         • account.abp.io (authentication discovery endpoint)
         • abp.io (Studio services/updates may use it)
       • If your company blocks unknown external identity providers by policy, you must explicitly allow these.

    4. Retry login

       • After DNS/proxy is fixed, reopen ABP Studio and login again.

  • If this is license/account related or you need your network requirements officially confirmed for your organization, please contact us: https://abp.io/contact

  hi

  The account website is no problem.

  Did you use a proxy service for the studio?

  Thanks.

  hi

  Based on the logs you shared, there is no direct error related to account.abp.io connection failure. The login-related entry only shows Login cancelled by user, which means the login process was interrupted before it could complete.

  Since you can open https://account.abp.io/.well-known/openid-configuration in your browser without any problem, the issue is likely specific to how the .NET application (ABP Studio) makes network requests, rather than a DNS resolution problem.

  Here are a few things you can try:

  1. Check if any antivirus or security software is blocking ABP Studio's network access. Try temporarily disabling it and then attempt to login again.

  2. Check Windows Firewall rules to ensure ABP Studio is not being blocked from making outbound connections.

  3. Try resetting the network configuration by running the following commands in an Administrator Command Prompt, then restart your computer:

  netsh winsock reset
  netsh int ip reset
  ipconfig /flushdns
  

  Additionally, from your logs, I noticed another issue: your machine is missing .NET 9.0 runtime. You only have .NET 7.0.20 and .NET 10.0.0-rc.1 installed.

  https://dotnet.microsoft.com/en-us/download

  ---

  BTW, is your Studio the latest version?

  Thanks.

  yes it's updated version and i also installed the NET 9.0 runtime but issue still persist. Since the URL https://account.abp.io/.well-known/openid-configuration is accessible from our end, it indicates that there are no network or DNS-related restrictions. However, we are encountering an error when clicking the login button in the ABP Studio application, which suggests that the issue may be related to the application itself.

  Thank you for the update.

  To help narrow down whether this is an ABP Studio application issue or a .NET runtime networking issue on your machine, could you please run the following command in PowerShell?

  [System.Net.Http.HttpClient]::new().GetStringAsync('https://account.abp.io/.well-known/openid-configuration').Result
  

  Or

  try {
      $handler = [System.Net.Http.HttpClientHandler]::new()
      $client = [System.Net.Http.HttpClient]::new($handler)
      $client.Timeout = [TimeSpan]::FromSeconds(30)
      
      Write-Host "=== .NET Runtime: $([System.Runtime.InteropServices.RuntimeInformation]::FrameworkDescription)"
      Write-Host "=== OS: $([System.Runtime.InteropServices.RuntimeInformation]::OSDescription)"
      Write-Host ""
      Write-Host "Requesting https://account.abp.io/.well-known/openid-configuration ..."
      
      $result = $client.GetStringAsync('https://account.abp.io/.well-known/openid-configuration').Result
      
      Write-Host "SUCCESS - Response length: $($result.Length) characters" -ForegroundColor Green
      Write-Host $result.Substring(0, [Math]::Min(200, $result.Length))
  } catch {
      Write-Host "FAILED" -ForegroundColor Red
      Write-Host ""
      Write-Host "=== Exception Type: $($_.Exception.GetType().FullName)"
      Write-Host "=== Message: $($_.Exception.Message)"
      
      $inner = $_.Exception.InnerException
      $depth = 1
      while ($inner -ne $null) {
          Write-Host ""
          Write-Host "=== InnerException ($depth): $($inner.GetType().FullName)"
          Write-Host "=== Message: $($inner.Message)"
          if ($inner -is [System.Net.Sockets.SocketException]) {
              Write-Host "=== SocketErrorCode: $($inner.SocketErrorCode)"
              Write-Host "=== NativeErrorCode: $($inner.NativeErrorCode)"
          }
          $inner = $inner.InnerException
          $depth++
      }
  } finally {
      if ($client) { $client.Dispose() }
  }
  

  • If this command also fails with the same error, it means the issue is with the .NET networking stack on your machine, not ABP Studio itself.
  • If this command succeeds and returns the JSON content, then we can investigate further on the application side.

  Please share the result so we can determine the next steps.

  Thanks.

  Hi,

  For a quick answer, if you login by using ABP Studio CLI, it should work on ABP Studio, too.

  As a workaround

  • Close all the ABP Studio instances
  • If not installed, install abp studio cli

  dotnet tool update -g volo.abp.studio.cli
  

  • Login by using CLI

  abp login
  

  Our team will post whenever they find the real solution, this approach should allow you to use ABP Studio at least

  Hi @zubair_Latif

  There is another possibility that, either Windows Defender or your Virus program might block ABP Studio to access an external URL. Are you using Windows Defender or any other Virus program ?

  We have been using Kaspersky on our system since the beginning, but the ABP issue has only started occurring today.

  Is it managed by your company or by you? Maybe you can temporarily disable Kaspersky and try again.

  It is managed by our company. The issue has now been resolved. It was caused by Kaspersky restrictions impacting ABP Studio’s network communication. Necessary adjustments have been made. Thank you for your guidance and support throughout this issue and everything is now working as expected
