Zhengzhou scene code transcoding display 2502

Network problems. Scene code, that is, the two-dimensional code that residents need to show when entering and leaving the community and taking the bus and subway, will have an error code of 2502 if there is network fluctuation in the use process, so the transcoding display of Zhengzhou scene code 2502 is a network problem. Need to replace the network with good network quality in time.
