Question posted in 
I recently migrated to a new server (CentOS with plesk 11.0) and installed a new SSL certificate for my domain.
Problem now is that any IE user has the error “there is a problem with this website’s security certificate” when they try to access the secure area of my site.
I’ve tested all main configurations – MAC/Windows/mobile plus browsers: FF,Chrome,Safari,Opera,IE and the only combination that gives me this problem is IE on windows. IE 11 works fine, all previous versions (the majority) come up with this error.
where do I start?? I can find no problem with the installation and this is obviously denting confidence in my site.

There are some known issues with IE and Certificates. Check these threads.

I found a work around for this issue. It is necessary to run https proxy which will accept certificate for Internet Explorer. I use a Python HTTP/HTTPS Proxy proxpy. You should point to required certificate file in core.py
DEFAULT_CERT_FILE = "./cert/ncerts/proxpy.pem". So you need to use proxy settings in Internet Explorer. It is 127.0.0.1:8080 for ProxyPy by default.
