The pictures on the seven cows are always inaccessible for the first visit every day.

  html5, question

The H5 page embedded in APP is placed in qiniu. some pictures are always hung up on the first visit every day, saying it is a network problem. other pictures can be accessed, saying it is a code problem. once or several more visits can be made, the problem is difficult to reproduce.

Fiddler is used to grab the package only once. The status code is 504, which is a proxy problem.

Is it caused by the instability of the proxy server of seven cows?

I also have such situations, every first visit will be delayed or unable to load, making the project very unstable. . . Submitting the work order cannot be solved. Now the code is tied up and it is quite passive to start all over again.
