SSL certificates made by WAMPServer generate browser error

Hi.

Just installed WAMPServer 3.4.0. I'm trying to enable HTTPS for the development site but I noticed that I'm getting an error in my browser that reads:

Quote

This server couldn't prove that it's php85.scratchpad.test; its security certificate does not specify Subject Alternative Names. This may be caused by a misconfiguration or an attacker intercepting your connection.

I know how to settle this error by providing the domain, in this case php85.scratchpad.test, in as an alt_name in the OpenSSL config. But how can I make the change to the script that generates the certificate to allow for this?

Should I run OpenSSL on my own first to make this change?

Yup got it. Managed to get it to work with the Manual method. Had to specify a SAN name.
