Modbus TCP client not reconnecting after modbus server goes offline

General
1

I am running a modbus TCP client (node-red-contrib-modbus) on a node red inside a docker container. However, when the server goes offline and comes online - it's not reconnecting - it shows "reconnecting after 2000 msec" message. Any thoughts to re establish the connection ?

What Nodejs version are you running ?

I think there is an issue with those nodes reconnecting when running nodejs higher than v12.
Read about this issue on the node's github page and here

How to check that. I am running this on a docker container using the following command

docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red

I believe this will fetch the latest version of all, how to change the node.js version ?

Plenty of tags to choose from ... Docker Hub

Thanks for that.
I pulled one image with node JS version 10.xx. It's working
