MVC HTTPS localhost Chrome connection not secure NET::ERR_CERT_COMMON_NAME_INVALID

Question

I have a website. It has an SSL certificate and I've had no problems until all of a sudden Chrome and Firefox won't accept my self signed certificate for localhost.

I've looked and found a lot of questions on this issue but haven't been able to fix it. Is there a step-by-step guide to fixing this?

I have followed this example https://stackoverflow.com/a/22818853/853295 but my certificate already has a Friendly Name with correct name.

Here's an image of my certificate

For Chrome you can just tell it to ignore the error. chrome://flags/#allow-insecure-localhost — Mike M, May 03 '17 at 15:22
That worked. Thanks for that!! I wish I could vote you up but I'm still too new for that. — joks, May 03 '17 at 23:54

Can this cause any problems or damage or have any detrimental effects? – Dov Miller May 15 '17 at 10:43
Do you know how to fix error for vhosts on localhost too? – suz May 16 '17 at 07:15
Dov - unless you are navigating to strange localhost sites there is nothing that I know of. – Mike M May 16 '17 at 19:16
@suz launch chrome with --ignore-certificate-errors that works on windows only – Syed Jafri Jun 29 '17 at 21:10
I tried this on Chrome v69, and it doesn't work. I restarted my browser and it still didn't work. Has something changed? (This is on a Mac.) – MiguelMunoz Sep 07 '18 at 07:32
