Gateway Invalid Protocol Version


I try to send data from my endpoint device to my chirpstack bridge server using helium. I can confirm that my bridge server can get the data but with an error. The error is:

time="2024-04-16T07:40:22.377677766Z" level=error msg="backend/semtechudp: could not handle packet" addr="ip-address" data_base64="yAIAOgAAAAAAAAAAgAgAAAAAAAEACAAAAAIBAIAKAAAAAwAAAAOADAAAAAdYcGFuc2WACAAAAAkAAQ==" error="gateway: invalid protocol version"

Is there someone who knows why I get the error and how to solve it
