We have configured our element to listen on a smart serial port, but it does not seem to be receiving data. The device that posts to this port has errors of "No connection could be made because the target machine actively refused it".
Looking on the machine itself, I can see that the port is not open (using Resource Monitor), but all 5 instances of SLPort are running and no apparent errors in the logs.
Where would you start to investigate? Please note that it will be very challenging to install wireshark so any other suggested tips would be appreciated (but if this is the only way then so be it).
Recently upgraded from DM9.6.10 to DM10.1 CU2 (unsure if related, but other environments do not have the above issue)
Hi Jack, Is this specific port opened in firewall?
In this case you configured “localhost” as IP Address when creating your element?
In this case, we use any – but we actually used a similar step to this to help diagnose. Thank you!
Hi Joey. Yes, the port is open on this agent. The communication is going via localhost
