You attempted to reach share.com, but instead you actually reached a server identifying itself as www.share.com. This may be caused by a misconfiguration on the server or by something more serious. An attacker on your network could be trying to get you to visit a fake (and potentially harmful) version ofshare.com.
It looks like the issue is that the website and Certificate identifying the website do not match. This is causing your error. You need to fix the certificate for this site.
