I have dedicated server hosting a number of my sites. One of the sites allows users to upload files (.doc, pdf, jpeg, etc). The uploading function works fine previously. But today when I tried to upload files (doc, and jpeg), my browser popup a security alert window saying "the identify of this web site or the integrity of this connection cannot be verified" with two warning messages: "the security certificate was issued by a company you have not chosen to trust" and "the name on the security certificate is invalid or does not match the name of the site",
At the bottom of the popup window, it says "Do you want to proceed? and three choices: Yes, No, and View certificate". when I click Yes, the text ".url" is added to the end of the file name in the file uploading box and the actual file is not uploaded after clicking the upload button. But if I upload a PDF file, it uploads just fine.
I did have a SSL certificate issued by a company installed for this domain which has its own IP that is different from the IP used by the server. The server does not have a SSL certificate. When I choose to View Certificate, self-signed certificate for the server is shown, rather than the certificate for the domain.
I have never experience such problem and could not find any clue on the internet. I tried FireFox and Chrome and both give me the same alert. Is it a problem with the SSL certificate or with my computer?
