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.

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.

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.

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.

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.

Reason

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.

Solution

Try manually increasing the gas limit (not gas price!) in your wallet before signing the transaction.

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.
