YOU can all check yourself for example also the virtualmin.com has this.
So i don’t understand this 2 times one with poison.?
CT Precertificate Poison: critical
0000 - 05 00
And also the ORANGE warning UNKNOWN FOR CRL?
Mechanism Provider Status Revocation Date Last Observed in CRL Last Checked (Error)
OCSP The CA Check ? n/a ?
CRL The CA Unknown n/a n/a (this one is WARNING in ORANGE)
Check here:
https://crt.sh/?q=virtualmin.com
Then result example:
crt.sh ID Logged At ⇧ Not Before Not After Issuer Name
2019-07-08 2019-07-08 2019-10-06 C=US, O=Let’s Encrypt, CN=Let’s Encrypt Authority X3
2019-07-08 2019-07-08 2019-10-06 C=US, O=Let’s Encrypt, CN=Let’s Encrypt Authority X3
the second for same date in that list has everytime the “POISON” in it.
at https://crt.sh you can check your server / domains handy for rate limits and co.
