# Clients can't create trading accounts via the B2CORE UI

## Problem

A client can't to create a trading account via the B2CORE UI and encounters an error.

## Possible reasons

This issue may occur due to one or more of the following:

* The connection to the trading platform is misconfigured or disabled.
* The product settings prevent account creation (for example, limits on accounts or deposit requirements).
* The product currency group isn't properly mapped to the platform.
* Client-specific account limits are exceeded.

## Solution

To check the required settings related to creating accounts on trading platforms:

{% stepper %}
{% step %}

#### Check the trading platform connection settings

* In the Back Office, navigate to **Products** > **Platforms**.
* Click the **Edit** button for the relevant platform to open its details.
* Click **Test connection** to validate the connection settings.
  * A checkmark on the **Test connection** button means the connection is properly configured.
  * A red **Test connection** button indicates errors in the settings, which will be listed.
* Correct the settings and test again until the connection is successful.
* Ensure the connection is enabled.
  {% endstep %}

{% step %}

#### Check the setting of the related product used for creating account on a specific platform

* In the Back Office, navigate to **Products** > **Products**.
* Click the **Edit** button for the relevant product to open its details.
* Review the following fields:

  * **Max accounts** – the maximum number of accounts a client can create per currency for this product. The client may have exceeded this limit.
  * **Min deposit amount (USD)** – the minimum deposit required to open an account. If the client doesn’t meet this requirement, the account can’t be created.

  For more details about these settings, refer to refer to [Products](/back-office-guide/products/products.md#details).
  {% endstep %}

{% step %}

#### Verify that the product currency is assigned to the correct platform group

* In the Back Office, navigate to **Products** > **Products**.
* Click the **Edit** button for the relevant product to open its details.
* Go to the **Currencies** tab.
* Click the **Edit** button for the required currency.
* Check the selected group in the **Platform group** dropdown and adjust it if needed. These are the groups created on the respective platform. The available currency options are limited by the settings of the configured platform groups.
  {% endstep %}

{% step %}

#### Check the limit on the number of allowed accounts in the client details

* In the Back Office, navigate to **Clients** > **General**.
* Click the **Edit** button for the relevant client.
* Go to the **Settings** tab.
* Review the fields:

  * **Max Demo Trading Accounts**
  * **Max Live Trading Accounts**

  If limits are set in these fields, they override the product settings. The client may have already reached the maximum number of allowed accounts. You can adjust the limits if needed.
  {% endstep %}
  {% endstepper %}
