    This isn't tech support this is for coding. Gas estimation fail is a generic thing returned for any error when trying to estimate gas, best guess, you didn't call approve first.

Are you trying it on Goerli or Mainnet? I happen to face these issues too and assumed my contract had an issue. However, all it required was just a refresh of the uniswap page to make things work again, I believe it is buggy recently.
