The Anki client setup documentation currently says:
Older desktop clients required you to define SYNC_ENDPOINT and SYNC_ENDPOINT_MEDIA. If using an older client, you’d put it as e.g.
http://192.168.1.200:8080/sync/andhttp://192.168.1.200:8080/msync/respectively. AnkiDroid also currently requires separate configuration for the two endpoints.
However AnkiDroid is a widely used app, but the suggestion that one should input /sync path string for SYNC_ENDPOINT is incorrect and leads to the vague error A network error has occured.
