SSL certificate for subdomain not valid, Alternative name Mismatch

Help
1

I did the same process for linuxcafe.ga and www.linuxcafe.ga and their SSL certificates are working fine.

My domain is: linuxcafe.ga
subdomains : myportfolio.linuxcafe.ga and www.myportfolio.linuxcafe.ga
I ran this command:
certbot -d myportfolio.linuxcafe.ga -d www.myportfolio.linuxcafe.ga
It produced this output:

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.

1: No redirect - Make no further changes to the webserver configuration.
2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you're confident your site works on HTTPS. You can undo this
change by editing your web server's configuration.

Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2

@jxstWieslaw Welcome to the community.

It looks like you have redirects working - at least from http to https. Please give example of what you want. Thanks

You may need to clear your browser's cache, the redirects are already working.
OR
Maybe they began to work once you restarted/reloaded Apache.
[a necessary part of that puzzle]
