When an exception occurs while fetching data, it is usually a problem with the code, or with the connection to the remote server. The first thing we need to do is check our code to see if there are any logical or syntactical errors, such as missing semicolons or accessing arrays out of bounds. If the code is OK, we can check the connection with the remote server. You can run the ping command to test the connectivity between the two servers. Alternatively, we can use the traceroute command to track the routing of packets between two servers to see if there are any exceptions.
In addition, we can also monitor the API used when fetching data to see if there are any exceptions. If you find an exception in the API, consider redeploying the API or redefining how the API is implemented.
//测试两台服务器的连通性 ping ip地址 //跟踪数据包在两台服务器之间的路由情况 traceroute ip地址
