WebClient gets 401 when requesting a directory without a slash - https

I have a web server using nginx, configured with HTTPS and Basic Authentication.
I'm attempting to query it with my WebClient with PowerShell
$wc = new-object System.Net.WebClient
$wc.Credentials = Get-Credential
return $wc.DownloadString($url)
This works fine with the following $urls
https://server.com
https://server.com/
https://server.com/directory/
https://server.com/page.php
https://server.com/directory/index.php
But for the following $urls, I get The remote server returned an error: (401) Unauthorized.
https://server.com/directory
https://server.com/otherdirectory
https://server.com/directory/directory
I thought at first it was due to redirection, but that wouldn't make sense given some of the working examples. Perhaps it's my nginx configuration?

I currently believe this is a bug in the WebClient class. Here is a summary of my interactions with the server:
------------------------------------------------------------------------

------------------------------------------------------------------------
At this point, the WebClient throws an exception, stating that the server returns the error stated in the question.
It should probably provide the auth token with the third request, or at the very least respond to the 401 with another request with the auth token provided.
I would like to have this confirmed by someone else (preferably with .NET 4.5.2) so I can accept this as the answer.

Laravel Scheduler creating thousands of log files in tmp folder

I have a Digital Ocean Ubuntu 16.04 server running Laravel.
I have a couple crons running every minute in the scheduler that trigger the Quickbooks API library. Everytime it runs it logs a text file similar to below. It creates a request and response txt file:

I don't need these logs created. How can I stop these from being created? I am not sure if they are being created from Ubuntu, Laravel or the Quickbooks API.
The bandaid is that I have a cron to remove these files from a shell script but I am trying to stop them from being generated in the first place. Thanks
It looks like a response from QuickBooks API. You can check here or here to find out how to disable or modify response log.

wget gives 403 on accessible files

First time poster with a bizarre issue I am having. I usually install software through conda, but from one moment to the other I stopped being able to use conda install because of a 403 I get from conda trying to access some configuration files. When trying to download those files with wget --spider --debug https://conda.anaconda.org/anaconda/noarch/current_repodata.json, I get the same 403 error.

Remote file does not exist -- broken link!!!
These files are accessible through the browser, and were always accessible with wget and conda until yesterday, when I was installing some tools not related to these network accesses. How can wget fail to download them?
So this was fixed by reinstalling apt-get. Some configuration file there must have been messed up.

Parse Security: able to see request/response in plain-text via proxy server

I'm attempting to hack the Parse SDK, and it seems that we are able to see requests and responses in plain text via a proxy server between Parse and the app. I assumed the data was encrypted, but a malicious user is able to see our requests and modify them to essentially pull out all of our user information.
Does anyone have any ideas on this?
Here is an example of a custom request and response via Proxy:

Drive Realtime API no longer returns realtime document on localhost

I have been calling the following gapi javascript function with great success for a few months:
gapi.drive.realtime.load(fileId,
successHandler,
initializer,
errorHandler);
Suddenly, at 1:30 PM CDT today, that call stopped working when run in javascript on localhost. I can deploy the exact same code to my server and it works perfectly!
Frustratingly, none of the callbacks are called - not successHandler OR errorHandler.
I have localhost:3000 set as an allowed javascript origin in my Google API Console project, and anyway I haven't changed any settings there since this was working. I am correctly authorized and can make REST calls to the Drive API without an issue.
Has anyone else seen this behavior suddenly? Can anyone from the Google team make a suggestion?
Update: the request inspector shows a GET to
https://drive.google.com/otservice/gs?access_token=[ommitted-for-stackoverflow]&id=[also-omitted]

Magento Soap API working locally but not remotely

I have created a custom API for Magento Enterprise 1.11. Calling the API through Soap v1 works fine on my local dev environment, however I am unable to make calls from my local environment to the remote environment.
Using PHP interactive shell on my localdev:
php > $client = new SoapClient(WSDL_URI,array('trace'=>1));
php > $client->login(API_USER,API_KEY);
php > var_dump($client->__getLastResponse());
string(538) "<?xml version="1.0" encoding="UTF-8"?>

I have been able to do this successfully from the localhost, as well as between two local VMs running on my dev machine. I can also access the methods of my custom API without issue.
However, when I try to make a soap client to my remote test environment, I am able to create the client, but the call to $client->login(), or any subsequent call results in the following:
php > $client = new SoapClient(REMOTE_WSDL_URI,array('trace'=>1));
php > $client->login(API_USER,API_KEY);

I've tried the "Content-Length" header fix mentioned in the sedond-to-last link, and just about everything else I could think of... Stumped.
While you can load the WSDL URL (http://REMOTE_HOST/index.php/api/index/index/wsdl/1/) from your computer, your remote server can't contact itself via its REMOTE_HOST.
PHP's SoapServer object (used by Magento's implementation) needs to contact the WSDL to know which methods are exposed.
For reasons I've never been able to figure out, it's a common network configuration for a server to not have access to it's own DNS entries. Connect to your server via SSH and try running the following
curl http://REMOTE_HOST/index.php/api/index/index/wsdl/1/
My guess is you'll get a network timeout or a REMOTE_HOST unknown error. Fix your configuration so your server can access itself, and everything should start working.
You could try changing host DNS nameservers perhaps.
