LMIC arduino does not join

Hi everyone,

I have setup the newest chirpstack server with docker-compose, then a tenant, added a gateway, an application, a device profile and an LMIC device according to Devices - ChirpStack open-source LoRaWAN® Network Server documentation → Generic Arduino LMIC-based devices

The gateway is online.
I start my arduino device an I see the following:


Starting
DEVEUI: 0xD4, 0x17, 0x45, 0x48, 0x5D, 0x16, 0x5B, 0x67 (in the ardunio code as lsb)
Packet queued
1890: EV_JOINING
84041: EV_TXSTART
477217: EV_JOIN_TXCOMPLETE: no JoinAccept

From the logs of docker-compose I see:

At the end a join_accept. But this doesn’t seem to be acknowledged by my arduino device.

Does anybody has an idea?

Best regards

p.s.: Is the LMIC code still supported and checked as I believe the code worked in earlier versions of chirpstack and lora server?

Funny, after I have restartet everything today, it works.
