Is using preferred-chain "ISRG Root X2" still a good idea? - Issuance Policy - Let's Encrypt Community Support
I have been using "ISRG Root X2" with acme.sh since the beginning, just curious if it is still needed after so many years, I switched to tlsserver profile and wondering if it still provides the shortest ECDSA chain if I omit the X2 flag in new servers. Just wanted to know if just using "tlsserver" profile flag is good enough for the short ECDSA only chain. Thanks.
