Why won’t my Canon EOS Rebel SL3 trigger some hot-shoe flashes?

I tried several flashes on my Canon EOS Rebel SL3, but some of them do not fire. Does the SL3 use a different hot-shoe trigger contact than the usual center pin, and what kind of flashes are compatible?

The T7/2000D, T100/4000D, and SL3/250D are all missing the big central sync connector on the hotshoe, which is the ISO standard signal for sync. This basically broke compatibility with any single-pin manual speedlight (e.g., YN-560 IV, or Godox TT600) which can only communicate that one signal.
And while firmware updates fixed compatibility issues with Godox's 2.4 GHz eTTL-capable speedlights for the T7 and T100, apparently those same updates do not work for the SL3. Only the Godox transmitters have received SL3-specific compatibility firmware updates.
If you need an affordable on-camera flash unit for the SL3, a Canon EL-100 is probably your best option.
But if you really need to use a 3rd-party single-pin flash, a Godox X1T-C or X2T-C transmitter can be used kind of like a hotshoe adapter to give you back the sync connection if you sandwich it between the hotshoe and the flash.

Generated from our catalog & community — verify before relying on it.
The EOS Rebel SL3/250D does not have the traditional large center sync contact on its hot shoe. That center pin is the standard trigger used by many simple single-pin manual flashes, so those flashes often will not fire on the SL3.
Instead, the SL3 relies on Canon’s dedicated hot-shoe contacts for communication and triggering. In practice, this means it works best with Canon-compatible flashes designed for those contacts, rather than basic ISO single-pin units.
So if your flash only depends on the center pin, it is likely incompatible directly on the SL3 hot shoe. Canon-compatible speedlights are the safer choice. Some users also use a compatible Canon/Godox transmitter on the camera as a workaround, then trigger flash gear through that.
In short: the issue is not a bad flash or camera hot shoe—the SL3 simply omits the standard center trigger pin, so compatibility with generic manual flashes is limited.
