Unable to connect getting server unreachable when using Brave browser but working fine with other browsers

I have also added proper cors headers in the code but still, it's not working only in the Brave browser. I have also attached the image in which the left window is Brave browser and the right window is Chrome.

Thanks for reporting this. Brave has settings that, by default, will block localhost connections. There are a few threads on this - one work-around is posted here https://community.brave.com/t/cant-turn-shields-off-on-localhost/41197/8 (it also seems there was a bug reported in Brave a few weeks ago that was fixed in terms of how it handles localhost exceptions to the shields that was apparently fixed recently). Did you try adding localhost (or maybe try it with 127.0.0.1) as an exception to blocking inside of Brave (per one of the threads apparently you can add @@127.0.0.1 as an exception in brave://adblock)?
