After a normal year and no changes on the server suddenly I'm getting:
Exit with code 1 due to network error: SslHandshakeFailedError
Error executing wkhtmltopdf! (Exit code: 1)
$GLOBALS['CREATEPDF_CUSTOM_SWITCHES'] = '--disable-smart-shrinking --page-size A3 --orientation Landscape --margin-left 0 --margin-right 0 --margin-top 0 --margin-bottom 0';
Any help would appreciated,
The first thing I would try is running the Test Server Requirements action from the plugins page to potentially narrow down if this is an issue on the server, or with something in the PDF you're trying to create. If all the tests pass, then I would start looking at the assets in the HTML you're converting to see if any come from other domains which may be having SSL issues.
I hope this helps point you in the right direction - let me know if you have any other questions!
Sorry to hear you haven't had any luck yet.
I was able to extract this file from the RPM, I believe it should be the wkhtmltopdf binary for CentOS 7: https://interactivetools.com/uploads/wkhtmltox-0.12.6-1.centos7.x86_64
Let me know if that helps!
