Fail to request https://sonarcloud.io/api/ce/submit?

I deployed my ‘dotnet sonarscanner’ on Centos8, and the Centos8 is run on ali-cloud.
The internet connection is ok, but sometimes I get following error after ‘dotnet sonarscanner end’. Need help and some clues about how to fix this issue, thanks~

Hey there.

Sorry for the late follow-up. Are you still facing a sporadic issue?

Yes. This issue is still here. I need some clues to about how to fix it.

just add some info:
[root@xxx scanner-report]# du -sh
16M .
the scanner-report folder files totally is 16M, does all the file will be upload to sonarcloud?
Does my issue is related to the report size? If yes, is it the limitation on the sonarcloud side or in my client that run the sonarscanner side?
