I am currently having an issue with PFC200 and exposed ports.
Upon bootup, two docker containers start successfully and are forwarded to ports:
- Node-RED 0.0.0.0:1880->1880/tcp, 0.0.0.0:8090->8090/udp
- InfluxDB 0.0.0.0:8086->8086/tcp, 0.0.0.0:8089->8089/udp
After a short while, external device (laptop) can easily connect to both ports.
Problem starts when ethernet connection is disturbed (by pulling a cable out) and reestablishing connection. Ports are still exposed and I have checked that processes on PLC are still running, but external device cannot connect to containers anymore given exposed ports. Restarting containers doesn’t fix the issue - the only way to fix it is to reboot controller.
I have checked and clear IPtables which also doesn’t solve the issue.
All other services like wbm or codesys visualisation work just fine.
Both containers are part of user-defined network with bridge model and fixed IP addresses within it.
I am trying to understand why is this happening - has anyone came across this before or have an idea what could be an issue?
