New GuzzleHttp does not honor proxy settings

Observed behaviour:
The new GuzzleHTTP Client code in LibreNMS/Alert/Transport/Api.php, introduced with PR #10070 does not honor proxy settings.
Thus breaking Api notifications in environments requiring a proxy.

Expected behaviour:
The new GuzzleHTTP Client code in LibreNMS/Alert/Transport/Api.php honors proxy setting from environment or config.php.

Validate output:
Note: Api.php has manually been modified with a workaround for said problem

Hi @kleinem86

Could you submit a PR with the fix for this ? We’ll be happy to review it and merge it for others using a proxy.



sorry i’m afraid providing a proper/clean fix myself is beyond my skills.

My workaround basically just hardcodes the proxy i’m using into the existing api.php file, into the argument array format guzzlehttp expects.
This can be found here:

I guess one would have to wrap a simple “if” clause around it to check if a proxy is globally set.
