This could be due to regulatory reasons (high-risk vertical) or technical reasons (server error, seller disabled payment method)
A more detailed explanation for these reasons are as follows:
Regulatory reasons: Tazapay is unable to accept payments using specific payment methods like credit cards for high-risk verticals.
Technical reasons: There may be a server error on our end, or the seller has disabled a specific payment method.
