Upload pictures to the server through Android. The company used a local area network before. It has been tested and can be uploaded normally. Then the background switches the local area network to the external network and uses the external network IP to upload pictures. There is a problem. This Is the problem an Android issue or is there something else? Has anyone experienced such a problem? Urgent reply, thank you!

Post a log and check the problem. If the external network can access it, then it’s a problem on the android side
