Hello @yelinaung, thnks for the issue.
Unfortunately I can't reproduce on my linux with the same commit.
Have you any way to test on linux? maybe using the docker container?

[yelinaung]

Hello @krichprollsch I am using Ubuntu Linux.

❯ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.2 LTS

just tried with the latest version again and the issue is not resolved on my end unfortunately.

ok, thanks.
FYI we have a work in progress regarding the HTTP client (and TLS client) which will introduce many changes and could help in your case.
I will let you know when ready.
