Answer 1

At OP request this answer details how to step-by-step, duplicate user environment in crond context.

In crontab, put a call to a shell script.

*/3 * * * * /home/userX/dir/exportmanager.sh

In the shell, echo or/and set environment before calling curl to have similar conditions of your own environment.

Https use SSL keys, how curl looks for this keys, in which certificate repository?

See --capath option.

#!/bin/bash
set VAR=value
/usr/bin/curl -k https://192.169.30.126/joomlandk2/index.php/exportmanager\
   >/home/userX/dir/exportmanager.log

It might be some special characters issue. Put the command into a wrapper script, add run permission rights and switch crontab to point to it.
