I'm pretty new to managing IIS (less than a week in), and I'm running into an SSL protocol error when trying to make a POST call. The problem started when I accidentally switched out certificates in IIS while working on my front and back ends. The front end seems fine, but I suspect the back end might have an invalid certificate. Even after trying to switch to different certificates from the dropdown, I keep getting the same error.
I've tried using the mmc tool, but it crashes whenever I try to add the certificate folder. I attempted to import the certificates to my personal folder through certlm, but the certificate provided by the client isn't validated by the system, and I can't find any issuer information online. I think the issues might have started when I changed the bindings, but I'm not sure what to do next.

Have you tried rebooting the server? Sometimes updating a certificate requires a restart of IIS. Also, check the frontend and backend logs for any clues about the error you're facing. They're usually very helpful for troubleshooting.
Good idea! How do I check the logs? If it's the one with the notebook icon, I don't think it had any messages, but I'll look again tomorrow. Also, is rebooting IIS just like running 'iisreset'?
