Hi,

I am new with pve and trying to set up notifications for my pve test server.

I have a ntfy server running.

If I do this from my pve shell:
Bash:
curl -H "Authorization: Basic <redacted>" -d "Look ma, with auth in header" https://ntfy.<redacted>.<redacted>/pve
Everything works fine.

But if I try the PVE GUI configuration for webhook notifications I cannot get it working.
I have tried many different configs and headers etc., e.g. I checked the wiki and I also tried to exaclty mimic what the curl call does.
Method/URL: Post https://ntfy.<redacted>.<redacted>/pve
I then added the Authorization header and used
Code:
{{ message }}
as body.
I also tried using defining secrets like described in the wiki.


Nevertheless, I always get:
Code:
Could not test target: io: Connection refused (500)
when I click the test button in the GUI

I would be grateful for any suggestions!
