Socket timeout issue

[HugoHumbert]

I ran my WDT between two dockers, both being in host network. I used the following ssh command :

sshpass -p password ssh -o StrictHostKeyChecking=no -p 52022 -o UserKnownHostsFile=/dev/null root@192.168.99.99 wdt -directory / -transfer_id f115f8bca955db40c614b8b9d9efe45c -start_port 22372 -overwrite=true | wdt -directory / -destination 192.168.99.99 -transfer_id f115f8bca955db40c614b8b9d9efe45c -start_port 22372 -manifest /tmp/tmp7s6rlqa9.tmp -overwrite=true

There seems to be an issue with the sockets, It worked fine in test but for some reason, I cannot get it to work in production:
