Debug: DStarRX: found frame sync in None

Repeater server with an IPr :

• raspberry Pi 4 
• STM32-DVM pihat Modem with firmware updated
• MMDVMHost
• Local IPr:62022
• Local IPr:20011

Gateway server with an IPg :

• DMRGateway  IPg:62022
• IrcDDBGateway IPg:20010

In MMDVMHost Log i’have this message :

[…]Debug: DStarRX: found frame sync in None

On MMDVMHost the tcpdump :

IP IPr.20011 > IPg.20010: UDP, length 26

The Repeater server send a good IP and port

In Ircddbgateway server log :

[..]Error returned from sendto (port: 20010), err: 22

On ircddbgateway server the tcpdump :

IP IPr.isdnlog > IPg.20010: UDP, length 26

The gateway receave ‘.isdnlog’ port and not 20011.

 The port is correct when i use tcpdump for DMRGateway

Why ? Sole body have the same problem ?

Thank you
