Symbiosis and removal of TLS-SNI-01 validation by Let's Encrypt


I noticed that Let’s Encrypt is no longer using TLS-SNI-01 validation.

I’ve updated certbot successfully on a couple of other sites (non-Bytemark hosted).

Will symbiosis-ssl on Bytemark continue to work automatically, or do users need to make changes?


I’m fairly sure it uses http-01. Regardless, I forced a renewal earlier and all’s good.


Yes, that’s right. There’s no problem for Symbiosis here.
