Crontab not running all @reboot services

Question

In my raspberry I'm using the following crontab to start two services at startup. The first one works fine but the second one doesn't (even though it works fine when I launch it manually). Any suggestions what could be causing this are highly appreciated.

# m h  dom mon dow   command
0 * * * * python pythonprojects/temperature_sensor/read_temperature.py
@reboot             sudo /usr/local/bin/pigpiod
@reboot             sudo /usr/bin/autossh -M 20005 -N -T -R22222:localhost:22 -i ssh-ec2/ec-key.pem ec2-user@xx.xx.xx.xxx

Remove the sudo and have this

directly in root's crontab or
in /etc/crontab having the user set to root
```
@reboot   root   command parameters
```

Cron is not able to interactively ask for sudoer's password.

If i do it with root; i assume it will ask some confirmation message the first time I connect. Is there a way to avoid that? – Nickpick Dec 01 '17 at 07:38
Not sure sudo is the problem because it works with the first line – Nickpick Dec 01 '17 at 07:39
With `sudo` you are already trying to run it as root. It's just not the correct way to do that. – Esa Jokinen Dec 01 '17 at 07:51
tried it but doesn't work – Nickpick Dec 01 '17 at 08:08
How can I debug this. is there a log for what happens then @reboot of crontab is launched? – Nickpick Dec 01 '17 at 15:52
