IIS Caching Deleted SSL Certificate

Question

I am using IIS 10 on Windows 2016

Whenever I update my SSL certificate and apply that to binding IIS doesn't use that but keeps using the old certificate.

Things what I have tried till now -

1. Restart website
2. Restart App Pools
3. Restart IIS
4. Deleting old certificate from IIS /Windows store

Rebooting Windows does solve it everytime.

Answer 1

If you have a firewall or Load Balancer, you will need to install the certificate there too. had same issue and that was the fix.
