NRV Reolink ang generic camera

I have a RLN8-410 & I’m using the generic camera integration with 6 cameras
I’m using this link to get a snap : http://xxx/cgi-bin/api.cgi?cmd=Snap&channel=0&user=xxx&password=xxx

The snapshots crash almost every days, but at random times, it seems because the images are captured too frequently.
Did someone manage to make it work ?
