Blank Page after restart . Agent submission issue

[Aly BERRY]

1) After installing C4 switch, I noticed that live does not work.
I installed the module.
After reboot of my server I have no access to C4 switch. I have a blank page.
"I have followed https://cookbook.denovolab.com/installation/troubleshoot-your-installation"
But still blank page

2) before that, I found out that it was impossible to create an Agent .
Nothing happens after submission

Thank you in advance for your answer.

Pls check the switch api status with this command -  systemctl status dnl_api_dnl

if the api is not running you can start it using this command -  systemctl start dnl_api_dnl

also pls check this doc for troubleshooting your install

https://cookbook.denovolab.com/installation/troubleshoot-your-installation

 systemctl status dnl_api_dnl =>   Unit dnl_api_dnl.service could not be found.

Hi Aly

After you reboot, api service was not started.  

I manually started it. 

[root@ns562457 ~]# systemctl start dnl_api_core

[root@ns562457 ~]# systemctl status dnl_api_core

● dnl_api_core.service - dnl api web service daemon

   Loaded: loaded (/etc/systemd/system/dnl_api_core.service; enabled; vendor preset: disabled)

           └─16843 /usr/bin/python3.6 /usr/bin/api_dnl_run

The UI should work now.
