Visualization shuting down after some time

    i have a problem with my Codesys Visualization, which runs on a Raspberry Pi.
    It functions perfectly during a short period of time after you have started the Raspberry, but after a few hours
    the Web-Visualization shows, that there is no connection. Error: "ERR_CONNECTION_REFUSED"
    Is there anything like a power saving mode which deactivates the Raspberry Pi or the Visualization or do you have another guess what the problem could be?

    Thanks for your Help,

    Hi Manuel,
    which runtime version is this?
    Please check the plclogger (login with CODESYS) for more information -

    Ohhhh, thank you,
    i looked through the Log-File (didn't know this exists) and saw, that the license was corrupted, so codesys used the demo function with only 120 minutes visualization-on-time.
    Thank's for your reply and help.
