Error writing events with webhook (Client.Timeout) and WebUI not updating.

[RyanLiu6]

Description

I'm seeing this error all over the logs for the registry container. My configuration is shown below.

time="2020-07-21T07:17:58.750029836Z" level=error msg="retryingsink: error writing events: httpSink{https://some.server.com:12443/v2/webhooks/events}: error posting: Post https://some.server.com:12443/v2/webhooks/events: net/http: request canceled (Client.Timeout exceeded while awaiting headers), retrying" 
time="2020-07-21T07:17:58.750065575Z" level=warning msg="httpSink{https://some.server.com:12443/v2/webhooks/events} encountered too many errors, backing off" 

Steps to reproduce

1. Run docker-compose up -d
2. Push some images
3. View the logs

• Expected behavior: Expect to not see errors about webhooks and see an update in the WebUI.
• Actual behavior: Seeing this being spammed every second and WebUI only showing events from when the container was spun up at first.

Deployment information

Deployment method: I'm following the sample compose file configuration, with some modifications, which you can see below.

Configuration:
Portus version: 2.5.0-dev@a1b9f2ebfeb84680a9dcd5629195e4c52815735c

Rake information for both portus and background containers can be found here
Compose files and other configuration can be found here.

I looked at several of the issues (specifically #2275 and #2241) but the suggestions were not able to fix my problem. Running curl on my server (host, not container) results in the following:

curl https://some.server.com/v2/_catalog -> list of images

curl https://some.server.com:12443/v2/_catalog -> list of images

curl https://some.server.com/v2/webhooks/events -> 404 not found.

curl https://some.server.com:12443/v2/webhooks/events -> 404 not found.

So I'm not quite sure what's going with my configuration and any help would be appreciated!

this issue for me seemed to go away after I increased the timeout value to 1500ms

notifications:
endpoints:
- name: portus
url: https://portus.domain.co.uk/v2/webhooks/events
timeout: 1500ms
threshold: 5
backoff: 1s
