Sometimes, when you visit your favorite website, you are greeted with various error messages, such as “404 Not Found”, “Microsoft Edge crashed,” “This site is not secure,” and “Server not found”. While some of them are not fatal, others can be very alarming as they may put you at risk for identity theft. One is the error message that involves the DLG_FLAGS_INVALID_CA error code.

What Is the DLG_FLAGS_INVALID_CA Error?

To be able to deal with the DLG_FLAGS_INVALID_CA error, you have to know what it is all about. In most cases, when this error code appears, it suggests that there is a problem with the website’s certificate. It could also mean that the site’s certificate is expired, not installed properly, or not recognized by your browser.

Generally speaking, this error code has something to do with a certain website’s certificate, which is something that can only be controlled by the owner of the website or an administrator. However, there are times when this error is triggered because of the default browser on the user’s end. If this is the case, you can try a few possible solutions to resolve it.

What to Do About DLG_FLAGS_INVALID_CA on Microsoft Edge?
