I'm trying to add a device to the DCR. We can access it using telnet but when LMS 3.0.1 says it's not reachable.
If I launch a "Management Station to Device" it says telnet OK. If we launch "Check device credentials" it says "Device not reachable" using telnet and we have insert the credentials several times so it's impossible to insert them wrongly.
What can be happening?
