Here's what Stripe said. (All this is new to me, so am learning a lot!)
About the EDCSA certs, what we have here are Root certificates for Stripe domains which you can further read here.
Those are useful for TLS connections TO Stripe; I'm under the impression that your issue is when Stripe is connecting to your server.
Please provide more detailed information on the exact error encountered [and the connection direction].
But earlier OP said:
Which suggests OP is indeed connecting TO Stripe..
The nginx after the above statement confuses everybody even further.
IMO OP needs to present a CLEAR problem with CLEAR logs/error messages which present the actual issue. Because I have seen none after 22 replies in 2 days already.
The list of root certs also contains a few ECDSA roots, so I'm doubting Stripe doesn't play well with ECDSA.
Webhooks are fairly standard as (exclusively) inbound Vendor->Subscriber requests, and Stripe operates with that pattern as well.
If they were having trouble sending data to Stripe, they'd would likely be talking about the "Stripe API", which is the outbound Subscriber>Vendor counterpart.
@jvanasco I agree but OP just isn't very clear
