Downlink problems after upgrade

[Dave]

Hi there
This looks like the same as:

Chirpstack 4.11 Downlinks No Longer Work - ResponseError: unknown command `GETDEL`

Hi, Since I have updated my Chirpstack servers to 4.11 downlinks no longer work. The downlink continues to stay in the queue and I get the following error message: ERROR chirpstack::downlink::tx_ack: Handling tx ack error error=An error was signalled by the server - ResponseError: unknown command `GETDEL`, with args beginning with: `frame:XXXXXXXXXX` I would be grateful for any support on this. Thanks

and

ChirpStack 4.11.0 - queued items not expiring

Hi there, I use NodeRED to send messages to a Kuando LED. After upgrading to 4.11.0, the first message is received and the LED illuminated to the colour I want. Any further messages are queued and not sent. The messages are marked as not pending. I send messages with a non-confirmed flag too. This code has worked for months and months. I guess something has changed? Can someone help?

Answer: Upgrade your REDIS
