lots of incomplete stripe payments started to appear

Ok so recently we have started to have “incomplete” failures from our stripe payments – and up until now stripe has been our go to rock solid payment option – I did wonder if it was the introduction of the 3DS2 protocol this week – but stripe was telling me that the 3D was completed but that it was then “waiting on an action”. On speaking to the stripe plugin guy he suggested that maybe another plugin was interfering with the “hashchange event action” in reply from stripe

So I looked at Cerber – now I had already done the required stripe whitelisting in the anti-span section for

/?wc-api=wc_stripe
/?wc-ajax=wc_stripe_get_cart_details

but when I start to look in more detail into the traffic inspector I was seeing a lot of stripe calls getting blocked i.e.

/?wc-ajax=wc_stripe_frontend_request&path=/wc-stripe/v1/cart/cart-calculation
/?wc-ajax=wc_stripe_frontend_request&path=/wc-stripe/v1/cart/shipping-address
/?wc-ajax=wc_stripe_frontend_request&path=/wc-stripe/v1/checkout/payment

So I have added these also into that white list section and I will monitor

This post is currently for anyone that might be seeing something similar

Also if I add

/?wc-api=wc_stripe
/?wc-ajax=wc_stripe*

in my whitelist with that last line wildcard cover anything else that might crop up?

thank you
