anyone have any idea what why I keep getting a "Gas estimation failed. Wait a few minutes and try again" message every time i try swapping a token on Uniswap. i am using metamask/ legder. i would appreciate any help.
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.
