I did my project in MEAN stack. I have installed GeoTrust Wildcard SSL certificate. It worked very well till yesterday. From today morning onward, it returns an error : "Your connection is private".
I don't know why this error occurs suddenly in any browser while run an application. It required to adding manually in exception lists to visit site. Right now I am not able to keep going my site. Certificate having 1 year validity and it was renewed in last month.
Please review attached images.
Give me guideline to solve this issue.
The certificate installed has expired. Looks like you have not installed or assigned the new certificate to your website.
