First, make sure your network connection is stable. If the network is unstable or the signal is weak, the upload may be interrupted. Try to reconnect to the network or change the network environment.
After confirming that the network connection is stable, try to upload the file again. Sometimes, a simple retry can solve the problem.
Close the application that is downloading, uploading, or streaming. These applications may use a lot of bandwidth and cause the upload to be interrupted.
Make sure the file does not exceed the limit of the website or upload tool. Also, check whether the file format is supported. Sometimes incompatible file formats can also cause upload problems.
Try to change the browser or upload tool for uploading, because different tools may have different efficiency and stability when handling file uploads.
Sometimes, firewalls or security software may block file uploads. Check the settings of these software to make sure they are not blocking your upload operation.
With the above steps, you should be able to solve the problem of sudden interruptions in the file upload process. If the problem persists, you may need to check your network environment or device settings more deeply.
