CRL ERROR: IOException occurred

[ITCMA]

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.

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:

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