I have currently two devices in my ChirpStack Application Server and these devices are functional.
I do not receive their messages in ChirpStack anymore and when I try to delete any of them, I get the following error message:
rpc error: code = Unknown desc = MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error. (code: 2)
How can I fix this ?
