pg_basebackup + SSL error: bad length

Hello,

I would like to create a streaming replication, when I'm trying the
basebackup from the node1, I've the following errors:

pg_basebackup -P -v -D ./main -h node1 -p 5432 -U repmgr

pg_basebackup: initiating base backup, waiting for checkpoint to complete
pg_basebackup: checkpoint completed
pg_basebackup: write-ahead log start point: 2/13000028 on timeline 1
pg_basebackup: directory "/srv/pgdata/tbs_int302" exists but is not empty
pg_basebackup: removing data directory "./main"

In the node1 postgresql.log:

LOG: could not send data to client: Connection reset by peer
ERROR: base backup could not send data, aborting backup
LOG: SSL error: bad length
LOG: SSL error: bad length
FATAL: connection to client lost

When I set off the SSL in the postgresql.conf, i've the folloving error
message when I try use the pg_basebackup command:
LOG: could not send data to client: Broken pipe
FATAL: connection to client lost

Have you got any information, suggestion how can I solve this errors?

My area:
