I have installed a Trap agent and certificate in Red Hat 6 successfully. But when I try to pull a Trap log. The error message occurs,  ERROR: 14090086: SSL routines: SSL 3_GET_SERVER_CERTIFICATE: certificate verify failed What could be for this error coming.   Linux error.jpg

Hi there,


Please see step 3 in the document listed at this URL:


Do you know if the 3 certs are trusted on the Linux server in question?

has anyone had luck installing Cortex Agent to Linux Mint 20? I have had no issues running Ubuntu Linux (20.04 LTS), but keep getting the "SSL Exception: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed" error on Mint.

Certificates are installed the same way as on Ubuntu, openssl verification to the server is successful.


Thanks, best regards
