Dear sir/madam, kindly assist with this peculiar issue only.
My WooCommerce store on Hetzner works perfectly when I test checkout myself. Real customers only are reporting failures at payment step. I have checked my IP is not rate-limited. The issue itself is reproducible only with certain customers in certain countries.
My setup:
- WordPress 6.5 on Hetzner shared plan
- Vultr as CDN/WAF
- Stripe for payments
- No caching on /checkout/* path
I cannot reproduce this myself. Kindly guide what debugging steps only I should take. Thank you very much.
