Bug Report

What version of TiKV are you using?

v8.5.3

What operating system and CPU are you using?

Steps to reproduce

See #18839.

At the final step we get the TiKV log which contained the download failure reason:

Cannot read http://<snip>.sst into /data/import/.temp/7ec17e4a-55dc-4376-aa8f-64b6ae866f02_16_1_67_write_2.sst: streaming error

What did you expect?

There should be further explanation about the cause of the "streaming error", e.g. Content-Length is wrong.

What did happened?

The error cause stopped at "streaming error" and we cannot get the underlying error.
