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
