Loraserver doesn't recieve any packets

I can see packets coming to the LoRa Gateway bridge in the logs (specified as pushData and pushAck) but those packets don’t seem to reach loraserver (LoRa Network Server).
Is this some configuration mistake?
I used to receive all packets quite well until this point.
