# Troubleshooting Errors

## **Issues on the Exchange**

### **INSUFFICIENT\_OUTPUT\_AMOUNT**

> The transaction cannot succeed due to error: INSUFFICIENT\_OUTPUT\_AMOUNT. This is probably an issue with one of the tokens you are swapping.

You're trying to swap tokens, but your slippage tolerance is too low or liquidity is too low.

{% tabs %}
{% tab title="Solution" %}

1. Refresh your page and try again later.
2. Try trading a smaller amount at one time.
3. Increase your slippage tolerance:
   1. Tap the settings icon on the liquidity page.
   2. Increase your slippage tolerance a little and try again.\

4. Lastly, try inputting an amount with fewer decimal places.
   {% endtab %}

{% tab title="Reason" %}
**This usually happens when trading tokens with low liquidity.**

That means there isn't enough of one of the tokens you're trying to swap in the Liquidity Pool: it's probably a small-cap token that few people are trading.

However, there's also the chance that you're trying to trade a scam token which cannot be sold. In this case, PancakeSwap isn't able to block a token or return funds.

{% endtabs %}

### **INSUFFICIENT\_A\_AMOUNT or INSUFFICIENT\_B\_AMOUNT**

> Fail with error 'PancakeRouter: INSUFFICIENT\_A\_AMOUNT'\
> or\
> Fail with error 'PancakeRouter: INSUFFICIENT\_B\_AMOUNT'

You're trying to add/remove liquidity from a liquidity pool (LP), but there isn't enough of one of the two tokens in the pair.

{% tabs %}
{% tab title="Solution" %}
**Refresh your page and try again, or try again later.**

Still doesn't work?

1. Tap the settings icon on the liquidity page.
2. Increase your slippage tolerance a little and try again.

### Out of Gas error

> Warning! Error encountered during contract execution \[out of gas]

You have set a low gas limit when trying to make a transaction.

{% tabs %}
{% tab title="Solution" %}
Try manually increasing the **gas limit** (not gas price!) in your wallet before signing the transaction.&#x20;

A limit of 200000 is usually enough.

The above example is from Metamask; check your wallet's documentation if you aren't sure how to adjust the gas limit.
{% endtab %}
{% endtabs %}
