Can I use LE in PWA & subdomain?

My domain is: still under development but it’s PWA

I need to have 3 domains as below

Yes, there’s nothing special about PWAs that prevent you from creating and using a Let’s Encrypt certificate.

Thanks for info but I’m not sure if I need normal SSL certificate / subdomain / wild card is needed in this case ?



You could use a wildcard certificate to cover everything under * or a certificate with multiple SANs to cover specifically and

An example of a multiple SAN certificate issuance can be found here.

certbot certonly --webroot -w /var/www/example -d -d -w /var/www/other -d -d

Please note that you should use the staging environment while testing because the production environment has strict rate limits.
