# Troubleshooting guide

> In this guide, we have listed the most common errors and how they can be solved. If the error would persist, please reach out to us at support@cryptolens.io.

<AccordionGroup>
  <Accordion title="Products are not showing up">
    If the products are not showing up, it means the product in Stripe is missing `skm_product_id` metadata parameter, which should be set to the product id of your product in Cryptolens. More documentation about this is available [here](https://help.cryptolens.io/recurring-payments/stripe-product-example#creating-a-product).
  </Accordion>

  <Accordion title="Products show up but not the plans">
    If the product names are showing up but not the plans, it means the *Pricing tiers* in Stripe are missing `skm` parameter in the metadata with information about the type of license to create. Please check out [this article](https://help.cryptolens.io/recurring-payments/stripe-product-example#updating-pricing-plan)

  <Accordion title="The Stripe webhook fails with 500 error">
    If the Stripe webhook keeps failing with an **500** error, the issue is one the following:

    * **The signing secret is incorrect** - typically, this error occurs if you first used Stripe’s *test* environment and then did not update the signing secret when moving to the *live* environment. We recommend to re-create the webhook and update the signing secret as described [here](https://help.cryptolens.io/recurring-payments/setup#webhooks).
    * **The API version of the webhook is incorrect** - Our Stripe webhook listener uses the webhook version **2018-09-06**. At the time of writing, such webhook can only be created using Stripe’s API. The solution is to re-create the webhook as described [here](https://help.cryptolens.io/recurring-payments/setup#webhooks).
