Random: nonblocking pool is initialized in KVM, no access to Plesk

Hello,
I upgrade services plan to more VPS 2018 SSD 3, and
made changes on my vps after the upgrade the partitions using this manual https://docs.ovh.com/gb/en/vps/repartitioning-vps-after-upgrade/
All changes were successful? and no errors. File system is ok. I reboot from rescue mode and after reboot vps, i cant connect to cpanel, plesk, not work http, dns, smt,https on status panel only ssh and ping.
This is my ne partition table
root@rescue-pro:~# mount /dev/sdb1 /mnt
root@rescue-pro:/df -h
Filesystem Size Used Avail Use% Mounted on
udev 3.8G 0 3.8G 0% /dev
tmpfs 780M 8.4M 772M 2% /run
/dev/sda1 2.4G 1.5G 769M 66% /
tmpfs 3.9G 0 3.9G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
/dev/sdb1 79G 19G 58G 24% /mnt
When run KVM console i see this on last lines:
Begin: Mounting root file system ... Begin: Runing /scripts/local-top ... done.
[ 487.802377] random: nonblocking pool is initialized

when connect in rescue mode and run "cat /mnt/sdb1/etc/fstab"
see result: LABEL=cloudimg-rootfs / ext4 defaults 0 0

I wrote of three support requests 24 hours ago, but there are still no answers
How to fix it?
