Vyzkoušet si to můžete na helloworld.letsencrypt.org.
Vyskusane a hahaha:
Pri pripájaní k helloworld.letsencrypt.org sa vyskytla chyba. Neplatný podpisový certifikát v odozve OCSP. (Kód chyby: sec_error_ocsp_invalid_signing_cert)
Stránku nemožno zobraziť, pretože pravosť prijímaných údajov sa nedá overiť.

Mnohem užitečnější než hahaha by byla informace o tom, který prohlížeč/OS takovou chybu ukazuje.

Myslím, že problém je v tom, že OCSP server, který je v certifikátu uveden, vrací na OCSP dotazy chybový kód 400 Bad Request. Zkoušel jsem to podle tohoto návodu: OpenSSL: Manually verify a certificate against an OCSP.
Všechny browsery, co jsem ale zkoušel, s tím problém nemají, buď proto, že používají data z OCSP razítek v TLS komunikaci, která nejspíš fungují*, nebo proto, že nefunkčnost OCSP berou jako soft-fail.
*) To se dá vyzkoušet takto:
