we have Updated our PRTG few days ago to ver. 220.127.116.119. Our Linux Servers with Linux Ubuntu 32 bit Ver. 12.04.4 LTS and Linux Ubuntu 32 bit Ver. 12.04.5 LTS giving the error code PE094. The device you want to monitor is not compatible. The sensor cannot parse the reply data.
According to release notes the problem was fixed with the ver. 18.104.22.1689
I have tried to recreate the sensor but the new one showing the same error.
