Similar issue here. Also intermittent, but is happening pretty frequently.
Customer clicks on Pay button. Stripe records payment. Sale is recorded in Woocommerce back-end.
However order confirmation page does not display and customers cart still contains the items.
Customer does not get any notification that the sale has happened.
In some cases after about 120 seconds we get the a Gateway Timeout message.
We’ve been using stripe payment without issue for a long period, but issue was first noticed about 4 weeks ago.
I will open a ticket on the woocommerce site…
