Answer 1

Flush Cache and Run Cron again.

php bin/magento cache:flush
php bin/magento cron:run

Answer 2

If flushing the cache with php bin/magento cache:flush doesn’t work for you, check the cron_schedule table and look for your Job Code there. Chances are one of the instances is stuck with status "running" due to some error in your observer. If so, just delete that line from the cron_schedule table and try running the cron again.

I think you need to restart your cron service in Host Server

Answer 4

The group with id "default" works with a period of every 15 minutes. Try to replace it with the "index":

...
 <group id="index">
...

Answer 5

You can use "which php" command to see the exact php path running on the server. Use that php path to configure by the SSH user used for the magento not by the root user.

Go to Magento installation and run

crontab -e

* * * * * path_to_php var/www/html/***.com/v2/bin/magento cron:run
* * * * * path_to_php var/www/html/***.com/v2/update/cron.php
