Hello,
We are having an issue with the Web Server Failing on the latest 4.0.165 Booter OS 4.0.269. Unit will function for a while and fail for unknown reasons. We must power cycle plc to correct issue. Port 502 and 28,784 work fine port 80 is locked up. We checked it with wireshark and when it works it works and when it fails the ecom does not acknowledge the request.
Help?
