RUT241 - Modbus - Daemon is down

I have device RUT241, with firmware RUT2M_R_00.07.04.3. I have trouble with Modbus TCP Server. I have correct set Modbus communication, but when i starting function “REQUEST CONFIGURATION TESTING” I get a message back : “Failed to send test request, daemon is down”.
Can I ask for advice, or what needs to be started or set?

Thank you for any help.

Welcome to Teltonika Networks Community !
It seems that the modbus itself is not configured properly. Kindly make sure that the mobus is enabled (First option) and saved.You can send a screenshot of the whole modbus configuration page (redacting sensitive information)
Also Update to the latest firmware, so that we can rule out Firmware related issues.

I am sending printscreens of Modbus TCP communication settings. Firmware RUT2M_R_00.07.04.3 still is same because I manage RUT241 remotely. Is it possible to solve the “daemon…” error from the attached images? Thanks a lot. M.

Now is communication OK. Just check the option “Always reconnect”. Thanks
