multi network test - java 2.6.2 times out on upsert

With java 2.6.2, tested against server build 6.0.0-1643.
setup a cluster in docker container and set external port, host that is mapped to docker host port.
Use that docker host as the ip and set mapped port as .bootstrapHttpDirectPort then create bucket which was successful.
then bucket.upsert failed with timeout.

SDK log is attached.

this is mapped port of one node

IP of the docker host is 192.168.1.149.
I was able to open console throuth the mapped port which was 192.168.1.149:37614 so, server is ready to accept operation.
