your are sending as a WSTRING which is UTF16, but your receiver is interpriting as UTF8. Change the receiver to use UTF16, or better change your sender to convert to UTF8. You publish the entire storage space (SIZEOF) Instead of the number of bytes of actual text (StrLenA) try using utf8JsonData : STRING(2000); JSON.Stu.ConvertUTF16toUTF8( ADR(wsJsonData), ADR(utf8JsonData), SIZEOF(utf8JsonData) ); and change your publish to mqttPublish( mqttClient:=mqttClient, pbPayload:=ADR(utf8JsonData), udiPayloadSize:=To_UDINT(JSON.Stu.StrLenA(ADR(utr8JsonData))),...

Hello, I think you can try to change the Connection from Multicast to Point to Point. Please also make sure your windows firewall is allowing the correct UDP ports inbound for ethernet IP. You might also need to increase the RPI, so it times out slower.

I think it is a similar issue, but different. I saw you use AWS IoT Core. AWS limits you in this - search in page here for text "Subscriptions per connection" it is 50, cannot be changed.
