Can someone share setup with jwilder nginx? Failed to connect to plugins.matomo.org port 443 Operation timed out.

Nobody has claimed this yet.

I have setup Matomo with jwilder nginx just for ease of use:

```
version: '3'
services:
nginx-proxy:
image: jwilder/nginx-proxy
container_name: nginx-proxy
restart: unless-stopped

```

and it's kinda working fine, however, randomly getting `2022/01/25 22:08:21 [error] 34#34: *586 FastCGI sent in stderr: "PHP message: Error in Matomo: curl_exec: Failed to connect to plugins.matomo.org port 443 after 30202 ms: Operation timed out. Hostname requested was: plugins.matomo.org" while reading response header from upstream, client: 172.16.198.2, server: , request: "GET /index.php?` errors. Any advice on that one?

Start with the Docker Compose services shown in the issue, especially matomo, matomo-web, and their frontend/backend networks. Reproduce the request and inspect connectivity from the Matomo container to plugins.matomo.org, including the relevant nginx setup; done means the endpoint connects reliably without the reported timeout.
