Why do ETH swaps fail?

Why do ETH swaps often encounter difficulties and fail to execute successfully? Could it be due to insufficient liquidity in the decentralized exchanges where these swaps are conducted? Or could it be a result of technical issues with the smart contracts underpinning the swap process? Additionally, could market volatility and sudden price movements play a role in the failure of ETH swaps? Clarifying these factors could help traders better understand the challenges faced during ETH swaps and potentially find ways to mitigate the risks associated with them.
