There is a small issue where a Plesk/CentOS 7 system is migrated to Azure and nginx fails to start.
This is the error in the nginx log
# cat /var/log/nginx/error.log 2018/06/14 22:11:41 [emerg] 9341#0: bind() to 10.144.114.11:443 failed (99: Cannot assign requested address)
If so then to edit:
# net.ipv4.ip_nonlocal_bind = 1
# sysctl -p /etc/sysctl.conf
#service nginx start
