My one-click Redis instance keeps logging that error:
174459:C 29 May 2026 19:26:46.081 # Failed opening the temp RDB file temp-174459.rdb (in server root dir /data) for saving: Permission denied
1:M 29 May 2026 19:26:46.181 # Background saving error
What can I do about it? My rails app using Redis is reporting errors as well:
Redis::CommandError: MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to 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. (redis://redis-on-koyeb.past-landfowl.internal:6379
As I’ve chosen the one-click deployment I have no control over the configuration…
