Files synchronization

Help IPFS Cluster
1

Hello, dear community, please help me to understand how files synchronization works.

Here is my scenario:
I have a running cluster with 2 peers. I added 1 file. After that, I connected a new peer -> Total of 3 peers. But when I did ipfs cat file_hash it stuck in response.

How I can get this file on the new peer?

This usually means that the 3rd peer is not able to reach the other two.

Check that they can connect (ipfs swarm connect).
