MQTT Fail until reboot

Good morning, I noticed some strange behaviour with MQTT
I’m using node-red to read/write data via MQTT to OpenRemote (Google Cloud)
I was looking at the GPS and it wasn’t updating, even if node-red was showing “connected” and the payload was correct. No logs in OpenRemote manager about errors
I didn’t try other attributes, but after a reboot of the OpenRemote VM everything was working again.
What are the possible causes of this issue? Next time it happens I’ll do a packet capture to see if Google is receiving the MQTT message
