Thanks, will try to fix that asap.

But... are there any "nextcloud" keys in the database? The error will also appear when there are no keys in the Redis database.

[ntimo]

I just checked and there are no keys named "nextcloud" they all have a name with a random number at the begging like this one:

"3326) "a3668cdd0c6904c1def0e53585ee9dcc/imagePath-fabc87e239c56532ea819c228014e1db-ransomware_detection-app-dark.svg""

I just did a redis-cli INFO keyspace and saw that there is only one database in redis:

# Keyspace
db0:keys=5697,expires=1552,avg_ttl=1411300535

[andryyy]

Strange. Why did I assume it was "nextcloud"?

We could use a dedicated Redis DB.

[ntimo]

I have no idea, I just found this command in the nextcloud.sh. But how can I get rid of all those nextcloud related keys without deleting the Mailcow keys? I think moving forward using a sperate Redis DB would be awesome.

[andryyy]

Don't know about identifying the keys. But I will add the change for a dedicated NC db soon.
