# 更新失败怎么办

## 1、检查订阅链接、如果是<mark style="color:red;">https</mark>开头失败，则改为<mark style="color:red;">http</mark>，如果是<mark style="color:red;">http</mark>失败，则反之

## 2、检查订阅链接，是否为<mark style="color:red;">tt</mark>.yesiamai.com开头，如果前缀不是<mark style="color:red;">tt</mark>，则改为tt

## 3、以上方法均无效？复制出订阅链接，并<mark style="color:red;">删除</mark>当前订阅，用复制出来的订阅链接<mark style="color:red;">重新添加订阅</mark>

## 4、直接访问tt.yesiamai.com检查是否可以访问，如果不能访问则说明域名被墙或域名在本地不可用，此时可以检查是否有可连接节点，通过节点开启<mark style="color:red;">全局代理</mark>更新订阅或者点击<mark style="color:red;">更新（通过代理）</mark>，如果可以访问，则说明有操作失误的地方，重新尝试以上方法

## 5、以上方法均无效，直接私聊我TG：@derrickill
