Certificate problems


since 20210924-070000 there seems to be a problem with your servers certificate.

curl https://status.ocr.space
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https:// curl.haxx.se/ docs/ sslcerts.html
curl failed to verify the legitimacy of the server and therefore could not establish a secure connection to it. To learn more about this situation and how to fix it, please visit the web page mentioned above.

Unable to locally verify the issuer’s authority.

It seems CURL is having problems connecting to Let’sEncrypt, our certificate issuer.

The certificate itself looks good and is valid:


but it’s not only CURL. Same happens for WGET…

and happens on different (LINUX) operating systems.

It’s strange but wget and curl work on a Windows 10 box…
no problems at all :frowning:

Als bekannt inkompatibel nennt Let’s Encrypt unter anderem Blackberry vor 10.3.3, Android vor 2.3.6, Nintendo 3DS, Sony PS3 sowie PS4 vor Firmware 5.00. Keine Probleme bekommen sollen Geräte ab Windows XP/SP3, Android ab 7.1.1, macOS ab 10.12.1, iOS ab 10, Ubuntu ab 16.04, Debian ab Jessie sowie Java 7 ab 7u151 und Java 8 ab 8u141.


Thanks for the info - very interesting!
