Connection is not successful with curl 8.5.1-DEV

[devkdas]

I built ATS as explained in the HTTP/3 Docs (https://github.com/apache/trafficserver/wiki/HTTP-3-Documentation)

is there any known issue with curl 8.5.1-DEV with ATS or am i missing anything here?

[brbzull0]

@Karthikdasari0423 try using the hostname(localhost) instead of the ip address, I suspect this is related to nghttp2 issue(or misuse not sure).

Thank you @brbzull0,

I placed all my files in /var/www/html
If I try to download file which is in above path then I am getting error
Any idea what configuration do I need to change and in which file

Could you please help me with this

For example i have a file like below

root@ubuntu:~# ls -lrth /var/www/html/test.pdf
-rw-r--r-- 1 root root 560K Dec 17 19:12 /var/www/html/test.pdf
root@ubuntu:~#

if i try to download test.pdf,i will get error cause my ATS is not pointing to /var/www/html

root@ubuntu:~# curl -k -v --http3-only -o /tmp/test.pdf https://localhost:4443/test.pdf
