Unable to build a cluster of ubuntu vms

I cannot build a cluster of two foundationdb ubuntu vm instances
the doc says i should copy my current fdb.cluster file content to the new ones: after that i should run fdbcli --exec "coordinators vm1:4500 vm2:4500"
but now i get this error:

> fdbcli --exec "coordinators vm1:4500 vm2:4500
Error: One of the specified coordinators is unreachable

Interestingly when clustering a ubuntu vm leader with a docker container instance everything works fine
I think there is something wrong with foundationdb packaged for deb

doc: Building a Cluster — FoundationDB ON documentation

P.S: this is how i run foundationdb on docker:

docker run -d --name fdb-docker --network host -e FDB_PORT=4501 foundationdb/foundationdb:7.3.43

P.S 2: i just openned a github issue on foundationdb repo at this address: Unable to build a cluster of ubuntu vms · Issue #12083 · apple/foundationdb · GitHub
