"System.ComponentModel.Win32Exception (0x80090308): The token supplied to the function is invalid" when TLS13 is enabled

After adding the below registry key to enable TLS1.3 on Windows Server 2022
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
The .NET Client application throws the below exception
System.Security.Authentication.AuthenticationException: Authentication failed, see inner exception.
---> System.ComponentModel.Win32Exception (0x80090308): The token supplied to the function is invalid
--- End of inner exception stack trace ---

at System.Net.Security.SslStream.AuthenticateAsClient(String targetHost, X509CertificateCollection clientCertificates, SslProtocols enabledSslProtocols, Boolean checkCertificateRevocation)
Is there anything i am missing? In the .NET Client application i had set the protocol version to TLS13.
Thanks in advance.

Try the below before you call the server if server is also on windows 2022+
Otherwise it will not work if server is not 2022+
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls13

Connection Refused - Redis for Data Protection Keys in ASP.Net Core 2.1

I'm going through this article from Microsoft:
https://learn.microsoft.com/en-us/aspnet/core/security/data-protection/implementation/key-storage-providers?view=aspnetcore-2.1
I am trying to do the following:
services.AddDataProtection()
.PersistKeysToRedis(ConnectionMultiplexer.Connect("localhost"));
Error Stack:

I am using Docker:
redis:
image: redis:alpine
container_name: redis
ports:
- "6379:6379"
Any ideas?

You need to reference the container and port
services.AddDataProtection()
.PersistKeysToRedis(ConnectionMultiplexer.Connect("redis:6379"));
I also added abortConnect=false" to configuration
REDIS_CONNECTION_STRING = "redis:6379,abortConnect=false"
var redis = ConnectionMultiplexer.Connect(Environment.GetEnvironmentVariable("REDIS_CONNECTION_STRING"));
services.AddDataProtection().PersistKeysToRedis(redis, "DataProtection-Keys");

System.NullReferenceException in System.Data.RBTree`1.Minimum(Int32 x_id)

I am occationally getting a null reference exception when running my bitcoin node (written in C# .NET 4.5). I have been trying various apporaches, but it keeps coming up, sometimes after a few hours, sometimes after the server has been running uninterrupted for days. I am unable to provoke the issue (cannot reproduce), and I cannot see the source of the .NET implementation of the red-black-tree either. It seems it could be an internal .NET bug related to clearing a dataset. I have an exception trace here. I would appreciate any feedback on how to either correct the issue or work around it, in case anyone has had the same odd experience.

--Edit, due to nature of initial comments--
Look at the innermost exception trace. This is a call to the standard DataTable.Clear() method, that is supposed to remove all from a DataTable. The rest doesn't really matter. In hindsight, I should have just posted that innermost exception.
Furthermore, I do not see the need to provide sample code, as one requested, since it obviously is internal to .NET. Most likely it is concurrency related, which I tried circumvent by wrapping all my DataTable.Clear() calls in a lock on a static object, and it still happens. The fact that it happens rarely and with random intervals is another good indication that concurrency is the issue. However, trying everything, I finally gave up and posted here, hoping someone else has this issue solved :)

An error occurred while connecting to Firefox ---> System.IO.IOException: The directory is not empty

I am working with selenium the last months. I use VS 2013 C#. Most of the time i am using webdriver.dll (2.39.0.0) for firefox (31.0.0.5310), because my testautomation (coded ui tests)
ran pretty stable with it. but now i get randomly this error:

I run it on 2 devices working with TFS. On one device it happens much more often.
I could not figure out the problem by now. Has anyone the same problem?

"Padding is invalid and cannot be removed." error with a twist

I'm getting the following error in our QA environment but only through the IIS7 reverse proxy. If I hit the application server directly it works fine. In our DEV environment it works fine through the proxy or directly.
I'm not really sure where to go with this, any ideas?

If this is happens on page with out post back then probably your proxy is convertting the url in lowercase chars and break the code.
I have one more bigger answer here with a trick to log the error and see whats really get on your page:
CryptographicException: Padding is invalid and cannot be removed and Validation of viewstate MAC failed
