Client Certificate not negotiated after server restart - iis

I'm using IIS Express 8 while my project is in development. I have a company certificate in the Personal folder of the computer account and several client certificates in the Personal folder of the current user account. I've successfully installed these using the mmc tool. I mapped the certificate and port for ssl with this command:
netsh http add sslcert ipport=0.0.0.0:44300 appid={} certstorename=MY certhash=some hash clientcertnegotiation=enable
When I run the app through VS, I am correctly prompted to choose a client certificate. However, when I restart my machine and run the app again, I am no longer prompted for the client certificate. Deleting the mapping and re adding it solves the problem..... unitl I restart again. OK, I have a workaround but it is far from ideal - I sense I'm missing something somewhere.
Any help greatly appreciated!

OK I sorted it now. The root CA certificate was NOT in the trust authorities store, but in Personal. For some reason this runs fine when adding the certificate (perhaps it's picking up the root CA certificate when running the netsh sslcert add command and caching it?).

IIS Client Certificate is Not Accepting, Not getting any Certificate Prompt

In one of my applications, I enabled the configuration on IIS to accept the client certificate, by enabling like the below picture. The same configuration I did on the local IIS server and it works.
but it's not working. Any configuration that I am missing..?? At least it should prompt for the Certificate.
It will prompt the client to provide a certificate only when accessing https:
You need to check whether to access the service via https.
I think you need to install the cert in cert store in current user for the browser to show up the dialog box with list of certificates

You get this error message when you are not using a trusted CA certificate. to resolve the issue you could try on of try below solution:
1)Click on the advanced button:
Click on the proceed to unsafe link:
Now you can work with the sell signed certificate.
This will only recommend when you are using sit internally. if you are hosting a site on internet it is recommended to use a trusted CA certificate.
or
2)ad the self-signed certificate to the browser ca store:

How to setup SSL on an IIS development server?

Our team has a Windows 2008 server which is used primary for a common IIS dev box.
I want to enable SSL on one of the websites on IIS, so that it can only be accessed via HTTPS.
I created a self-signing certificate in IIS and installed it. However when I access the website via the browser (Chrome, Firefox or IE - doesn't matter), it always gives the scary..."this is not secure" screen. I've tried installing the certificate on my own computer, rebooting and I still get that screen.
One thing that I noticed is when I create a self-signed certificate, it adds the domain name to it...for instance, the name of the box is webIIS and our login domain is COMPANYDOMAIN. So it will say that the certificate was created by webIIS.COMPANYDOMAIN.com. This url resolves to nothing, since there is no such thing.
Am I going about it the wrong way?
I've answered a similar question here.
Few afterwords:
Your server should have a dns name. If it is in a domain (Active directory or something) it surely does. Find it, use it in CN of the SSL certificate.
CA that will issue SSL certificate should be trusted by clients accessing the server and by the server itself. Place CA certificate in Trusted Root Store (in LocalMachine store) on the server and all clients that will access it. If you have Active Directory it should be pretty simple to distribute it.
CRL that CA has to issue in defined intervals (it's up to you if the CRL will be issued one a day, month, year or lifetime) has to be accessible by clients and server. Either place it at http url that you gave when issuing SSL certificate or manually place in each certificate store (in Trusted Root Store).

SSL Certificates Popup in nodejs

I have installed SSL on node server. I have made changes in app.js too.
Now when i am trying to run my website

I am getting Popup like this
Why i am getting this popup?
Is certificates doesn't installed correctly?
Thanks
The browser is asking you if you wish to authenticate yourself to the server using a certificate.
Clearly you have a certificate and a public/private key pair attached to your local account, or it wouldn't be asking you.
Simply click cancel if this is not intended.
Use the Windows Certificate Manager to check what certificate it is. In all likelihood you have installed the server certificate as a personal certificate on your account.

IIS with mutual SSL not workin

I'm new to mutual SSL. Therefore my understanding how client certifcates might be wrong.
When using Client certificates in IIS, do they need to be issued from the same certificate (or CA) as the IIS HTTPS binding has configured?
My dev IIS has a self signed certificate.
For the client certificate, I've created a CA and a Client certificate according to
the post here.
The CA is in my "Trusted Root Certification Authorities" of the local Computer.
The Client certificate is in my personal certificate folder.
On IIS I've set Client certificates to accept.
The first strange Thing is that when I browse to my page, the IE always shows me 403.7. Even I've disabled the IE setting "Don't prompt for client certificate selection...", there is no window opening for the certificate selection.
Also when accessing the page with a HttpWebRequest with Client cert attached, the response is always 403. Unfortunately there I did not figure out how to get the sub status.
Why doesn't IIS accept my Client certificate when the RootCA of the Client certificate is in the trusted root store?
Is there a way to get more details where the problem might be?
Thanks
Thomas
Finally could solve the issue:
The CA and Client certificates which I generated according to the tutorial here did NOT have the private key assigned in the certificate store. I had to remove the certificates from the cert store and Import the PFX file including the private key.
Second, the client certificate needs to be in the Current User/Personal store so IE does pick it up. I initallly generated it in the Current Computer/Personal store.
There might be a direct way how to create the two certificates including Private key with makecert. But the PFX import was the easiest way for me.
After 3 days of try and error on my side: If you use IIS10 on Windows2022, TLS1.3 is turned on by default.
The SSL handshake seems not to be implemented correctly in browsers/curls/.... for this case.
For testing reasons turn off TLS1.3
In
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server
Add:
DisabledByDefault as Dword with 1 and restart the server (not only IIS!)
