Of course your problems is with the high latency cloud servers.
You are using 9.4 so this is the time to use the feature introduced in 9.4 called : replication slots.
Read the docs, replication slots address the problems you are now facing.

Hi,
- max_replication_slots is 0 the default value
- it is internal network 1GB
- How can I check this? I think all my wal files are 16MB
Samed:
My Postgres version is 9.4 and I use the refresh command.
I have also to notice that I have 4 replication servers and the problem happens most of the times in cloud servers. In bare metal server, most times refresh works without problem.
