Hello Matthias,
Hi Peter,
thanks for noticing this.
No problem - should I open a "Bugzilla" for this?
Yes, you can do that if you want to in the Infrastructure section.
Best, Matthias
This happens if a server presents a certificate with the "OCSP must stapling" flag set, but does not supply valid OCSP information at the same time. Since OCSP has some major disadvantages if used by clients (DoS vs. fail-open behaviour, privacy issues, etc.), "OCSP must stapling" is generally considered to be a better option.
As far as I am concerned, we have those flag set on all of our certificates except for mail01, as mail server usually do not support OCSP.
I can confirm visiting https://patchwork.ipfire.org/ shows the same error, in several browsers and from several countries. Forum, Wiki, et al. seem to work fine. This looks like a server configuration issue, the certificates issued by Let's Encrypt are fine.
@Michael: Could you have a look at this?
Thanks, and best regards, Peter Müller
Hi,
today, suddenly patchwork.ipfire.org stopped working. Reloading the page several times doesn't help. Firefox 69.0.3 keeps telling me:
***SNIP*** Secure Connection Failed
An error occurred during a connection to patchwork.ipfire.org. A required TLS feature is missing. Error code: MOZILLA_PKIX_ERROR_REQUIRED_TLS_FEATURE_MISSING
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem. ***SNAP***
Setting "security.ssl.enable_ocsp_must_staple" in about:config to "false" temporarily fixes this, but could it be that there is a problem with the "Let's Encrypt" certificate!?
Can anyone confirm?
Best, Matthias
