Virtual interfaces, some works, some not. Same netmask & subnet [closed]

I am using Ubuntu 18.04.
I am trying to setup VPN (ethervpn) virtual IPs.
Basically imagine that there are dozens of dedicated machines all over the world.
Each machine should be running Ubuntu + Docker.
There are many different apps, replications, etc. in total hundreds of instances of different types, and domains.
So each server needs a lot of different virtual IPs so I can manage whole deployment.
I will use SQL databases as an example.
I have created using
ifconfig vpn_vpnclient:1 10.1.1.1 netmask 255.0.0.0 up
X.X.1.1, X.X.2.2, X.X.3.1, X.X.4.1, X.X.5.1, X.X.6.2, X.X.7.3, X.X.8.2
On remote machines those IPs are not always reachable.
I.e. 1.1 is working, but 2.2 not, 3.1 is, 4.1, 5.1, 6.2 not, 7.3 is and 8.2 is not...
All interfaces are created in init.d after vpn_client is started...
I have no idea why some of those IPs would work and some not.
There is no duplication (it is a new infrastructure), whole network is using netmask 255.0.0.0 due to big number of different apps, layers, etc.
Of course host can reach all IP's.
I do not use netmask as seems it cannot create virtual interfaces.
BTW often some are reachable, some are not.
I.e. 3.1 is not reachable after few restarts, but was working.
When I was creating them manually earlier this morning i.e.
5.1, 6.2, 4.1, 1.1, 3.1 worked.
Now 3.1 stopped working :)
