1. The system is busy. When the system is busy, the export request may be rejected by the server or timed out. You can try again later, or contact your system administrator to check the server status.
2. The network is unstable. Unstable network connection may lead to data transmission errors. Try checking the network connection or changing the network environment, and then try again.
3. The amount of exported data is too large. Exporting a large amount of data may cause the server to respond slowly or fail. Try to narrow the export range and export it several times in batches.
4. The export format is not supported. If you choose an export format or parameters that are not supported by the hownet paper management system, the export request may fail. Try to change the export format or check whether the parameter settings are correct.
If the above methods still cannot solve the problem, you can try the following methods:

2. Replace the browser. Try using another browser, or upgrade the existing browser version, and then log in to the background system again to operate.
3. Contact technical support. If all the above methods fail, you can contact the technical support personnel of HowNet Paper Management System for further help.
