Clarification: The presale website (not presale contract) got many users to connect to the default node (either for sending transactions or getting info from Vite blockchain) and overwhelmed it.
Solution: presale website should've used a node other than the default node.
澄清：预售网站（不是预售合同）让许多用户连接到默认节点（用于发送交易或从Vite区块链获取信息），并将其淹没。
解决方案：预售网站应该使用默认节点以外的节点。
