I was wondering how many indiehackers are using this free SSL service - https://letsencrypt.org/
Renewal is a bit of a pain, but it can be automated via scripts/tools available on various platforms.
We tried to use it in our product (https://www.feedbackrig.com/) which is a b2b platform. Therefore, we create sub-domain for each of our client. However, we faced various issues in generating certificates for wild-card sub-domains and we ended up buying a SSL cert with wild card support. I was wondering if anyone had faced similar situation and want to share their experience with LetsEncrypt ssl for wild card sub-domain.
