i use moodle 3.8.2+ (Build 20200312, latest Adaptable Theme) which is hosted on a Synology DS918+ with DSM 6.2.2. (Linux based OS). Apache 2.4 is set up as web server together with PHP 7.3.11 and a Maria DB 10.3.
I currently have the problem that blog images inserted via the atto editor's text field are not displayed on both the mobile app (version 3.8.2) and the Moodle desktop application (https://mobileapp.moodledemo.net/). This phenomenon is reproducible at any time, even after switching to the Boost theme. Videos or images in the file attachment, on the other hand, are transferred without any problems. When looking into the network activities of the Chrome developer tools, only the message 404 for the missing image resource is displayed. I would be very grateful if someone could help me in this matter.
