Error while downloading files

Description of the issue:
Whenever I want to download files from my university’s home page and from here only do I get this error that is totally unrelated to downloading files:新增票卡失败(unable to add new card)

This has only been encountered on my iPad, both my phone and MacBook works flawlessly.
How can this issue be reproduced?

2.open any class’s attachments
3.try to download a file
4.die

Expected result:
Successfully download the file and saved to local storage

Additional Information:
The attached picture is the error message I have been encountering recently. This has been troubling me for two weeks. During this period I have tried most general solutions: reinstalling brave, clear cache, restart iPad and so on, but none of the above yield any results.
