CRL ERROR: IOException occurred #975

Open ITCMA opened 1 month ago

ITCMA commented 1 month ago

Hello together,

since 1-2 weeks i see on orange warning at "Revocation status". It says "Good (not revoked) CRL ERROR: IOException occurred" - see the attached file. https://github.com/user-attachments/assets/5a5985dd-6061-47a7-9155-5b58347ab5a1

Unfortunately i see this error on many of my customer environments, but it looks like there is no impact. There are different CAs like Thawte. I do every time a hardening via Citrix NetScaler with result A+.

Does anyone else have this message and what does it mean?

Regards, Michael

Simply ignore it, the reason why you only see this now is because this went live on June 6th: https://letsencrypt.org/2024/04/12/changes-to-issuance-chains

Everything is working fine on our end. SSL Labs needs to update their scanner.
