Hello,
I am running a “small cute” Nextcloud instance. Everything seems to work perfectly fine, but after upgrading to latest v32 I see this line coming up in the log.
System is Ubuntu server 24.04
Nextcloud 32, apache, postgresql, php-fpm, redis
Running perfectly fine (…… “perfectly” ?)
Info
no app in context
The app config key files_external/user_certificate_scan is not defined in the config lexicon
I got no clue what or where to fix 
Anyone?
TIA
