Artisan serve "Closed without sending a request"

I got a strange issue with the wire:click event. Not sure whether it make sense to show the code, because this button is inside a dropdown, which is inside a table with many columns. Anyway:
Livewire event is attached to the this button, method present in the component. When I click on the button there is no network activity in devtools of the browser, but the console (php artisan serve) shows interesting reaction on the click: Closed without sending a request; it was probably just an unused speculative preconnection

All other components seem to work fine. Does anyone had something like this?

That “not sent request” was possibly caused by a bootstrap dropdown (or it’s modification) and the whole issue was a typo… in “wire:click”.
:slight_smile: Sorry for bothering you with that.
