Restic is not working.

[uncharted-user]

I was trying to back up using Restic and Rclone but connection getting refused. What am I doing wrong or Restic is not supported?
$ restic -r rclone:Internxt:TestWebDav init

enter password for new repository: 
enter password again: 
rclone: 2024/09/21 22:44:26 Failed to create file system for "Internxt:TestWebDav": read metadata failed: Propfind "https://webdav.local.internxt.com:3005/TestWebDav": dial tcp 127.0.0.1:3005: connect: connection refused
Fatal: create repository at rclone:Internxt:TestWebDav failed: error talking HTTP to rclone: exit status 1

$restic -o rclone.args="serve restic --tpslimit 10 --no-check-certificate" -o rclone.timeout="5m" -r rclone:internxt:test init

Fatal: create repository at rclone:internxt:test failed: error talking HTTP to rclone: Get "http://localhost/file-9234737688660035538": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

I then manually created the repository in my local drive and uploaded it but still not working!
$ restic -o rclone.args="serve restic --tpslimit 10 --no-check-certificate" -o rclone.timeout="1m" -r rclone:internxt:test backup /home/silverplate/Pictures/TestKoofr
