Upgrade TTS Open Source Edition from v3.13.3 to v3.18.1

Hi everybody,

We are trying to upgrade our On-Premise deploy of the TTS from v3.13.3 to v3.18.1.

We have followed the steps detailed in:
https://www.thethingsindustries.com/docs/getting-started/upgrading/

After performing them and without receiving any errors on deploy de docker stack, we see that we receive any data from the registered devices.

What are we doing wrong? Any advice?

Addenda: In the console we get the next error

“data”: {
@type”: “type.googleapis.com/ttn.lorawan.v3.ErrorDetails”,
“namespace”: “pkg/redis”,
“name”: “store”,
“message_format”: “store error”,
“code”: 2
}

Thank you very much.

Kind regards,
