HTTP/S Proxy for Telegram does not work

[Goncharov Sergey]

There is a proxy parameter in the spec. But not all types support it. For example, telegram does not support link.

I spent a lot of time to understand this. Shouldn't all types support this setting? Or at least have a mention in the documentation that they don't support proxies.

I think this is bug, HTTP/S proxies should work for all providers.

I believe this issue also applies to the git commit status update providers as well. None of them appear to have proxy support via the spec.proxy element
However, by kustomizing the notification controller, you can set HTTPS_PROXY/NO_PROXY and the client will use it
