Reboot mysql database, vtiger-demo_mysql_1 did came backup but the vtiger-demo_nginx_1

[tdsan]

I installed the software on Friday (6-26-2020), the software seemed to work fine but after a reboot of the server or after restarting the "vtiger-demo_mysql_1" the nginx container did not come up.

I cannot connect to the vtiger-demo_nginx_1 because it is down, is there a way to fix the problem.
