Hello!
I am running V4 - Docker on opensuse 15.4. Everything runs smoothly except one (important) thing. I can’t figure out why Chirpstack drops uplinks from devices occasionally. The logged error looks as follows:

I have the same error on both RAK WIsGate Developer gateway and several 1-channel test gateways (EU868 and EU433). The uplink is visible in gateway logs on Chirpstack and on gateways, but error is reported in Chirpstack log.
