Why won't Uniswap let me swap?

Why is it that when I try to swap tokens on Uniswap, the transaction fails or doesn't go through? Could it be due to low liquidity in the pool I'm trying to swap from? Or is it possible that there's a technical issue with my wallet or the Uniswap platform? Additionally, are there any specific requirements or restrictions that I may be unaware of that could be preventing me from making a successful swap? I'm seeking clarity on why I'm unable to complete my swap on Uniswap and how I can potentially resolve this issue.
