Cannot connect Conbee2 using Docker on Synology DSM7

I am running latest deconzcommunity/deconz in docker container on Synology NAS DS218+ with DSM 7.1.1

I can see the ConbeeII using lsusb -cui
|__1-1 1cf1:0030:0100 02 2.01 12MBit/s 100mA 2IFs (dresden elektronik ingenieurtechnik GmbH ConBee II DE2122650)
1-1:1.0 (IF) 02:02:01 1EP () cdc_acm tty/ttyACM0

I have added the dialout group with rw to root and user

But when I start the container I get this logfile
17:20:34:168 COM: /dev/ttyACM0 / serialno: DE2122650, ConBee II
17:20:35:112 reconnect network failed, try later
17:20:35:112 start reconnect to network
17:20:38:167 COM: /dev/ttyACM0 / serialno: DE2122650, ConBee II
17:20:39:167 COM: /dev/ttyACM0 / serialno: DE2122650, ConBee II
17:20:40:111 failed to reconnect to network try=1

And when opening phoscon app the firmware says not connected.

I am using the webUI port 80 and nothing else is using this port.

I have the ConbeeII on a extension cable and I have tried with two different ConbeeII with same result.

Can you add some longer logs?

Sure - which ones are relevant?

Can you add logs with log levels
Aps, aps l2, info, info l2, error , error l2.

There should be something in the logs with “reason” followed by a number.
