Except this one message everything looks good.

The websites are down because the let's encrypt cannot be renewed ... chrome says: unsecure connection.

Please help!

Try to run
# plesk installer --select-release-current --reinstall-patch --upgrade-installed-components

and then

# plesk repair installation

if this is not helping take into consider to contact Plesk support directly
