Yongnuo 603 flasher test triggered normal flashing, but the flash did not flash when shooting. What happened?

What is the flashover distance? Are there any glass cabinets and other things that affect infrared transmission at the shooting scene? If not, try replacing the battery. Flash leakage is usually a battery problem. When it is connected to the camera, wipe the bottom contact of the camera hot shoe and flasher with alcohol. If leakage occurs after these works, it is recommended to send them for repair.
