No COAP response from Thingsboard server

Question

I'm trying to send COAP telemetry to Thingsboard server: echo -n '{"temperature": 25}' | coap post coap://10.159.22.65/api/v1/MkGArynJPQKXZOuCsFm3/telemetry as in documentation. I get timeout. There is no firewall issue. I receive UDP packets on server: tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes 19:15:19.601050 IP 10.159.22.67.54666 > fliot-cms-prod-01.coap: UDP, length 67

But no answer from server. COAP is enabled in config: coap: # Enable/disable coap transport protocol. enabled: "${COAP_ENABLED:true}" and when I send COAP telemetry directly from server machine it responds ok - telemetry is stored.

[root@tb-server ~]# echo -n '{"temperature": 25}' | coap post coap://10.159.22.65/api/v1/MkGArynJPQKXZOuCsFm3/telemetry (2.03)

Also sending telemetry via HTTP API from remote machine works. Just COAP ... Any ideas? /Czarek
