Integration log errors after set-up

[Kolia56]

Your integration is more than welcomed, thank you. I set-up HA integration as per following :

http://HA_url:8123/api/chirpstack_http/lora

and I have added in Chirpstack HTTP integration with this field

http://HA_url:8123/api/chirpstack_http/lora

HA log reports the following:

HA and Lora gateway are running on the same subnet.

The unique sensor is delivering data every 20' but no entities are created at HA level. Is there anything you would need to troubleshoot?
Running HA 2025.05.0 and LPS8v2 (ie Chirpstack 4)
