Website hosting Oauth SSL callback error -- 2

I have a custom domain on which I am using oauth. The site loads properly but after oauth I get following errors. 'Warning: Potential Security Risk Ahead even though the site is in https.' On Firefox : Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for <domain name>. The certificate is only valid for the following names: [login to view URL], [login to view URL] Error code: SSL_ERROR_BAD_CERT_DOMAIN On Chrome : NET::ERR_CERT_COMMON_NAME_INVALID ----- I am using Heroku with GoDaddy custom domain. The heroku app itself works properly without any issues. Heroku has paid version ( 7$ ) with automatic certificate management (ACM). ------------------------------------------------------------------ I can give TeamViewer access to my PC which has admin login to GoDaddy and Heroku.
