DotRas 1.3 dial created Vpn entry error from application but not from Windows - vpn

I'm using dotras to create a vpn connection. When I try to connect to the vpn using the dotras dial async method it doesn't work:
"Error 718: The connection was terminated because the remote computer did not respond in a timely manner".
So I tried connecting to the vpn connection i've just created via the windows interface and it works just fine. Strangely enough, I then tried to connect again via the dotras method and it worked!
So, if I try to connect first via dotras I can't, but if I connect first via windows, disconnect, and then connect again via dotras it works.
I'm using Windows 10 pro and Windows 2012 server and the version of DotRas is 1.3

Xamarin Forms iOS will not fully connect to Wifi Access Point that has no internet access

I have a Xamarin forms application. The application programmatically connects to a an access to point to communicate via sockets with a host machine connected to that same access point. The access point is not required to have internet access. When testing my code in iOS - I get a socket error stating that the 'Destination is unreachable'. However, if I go to settings and click on the wifi connection I want to use - I am taken to the login page for the access point. If I click cancel I get the option to 'Use without Internet'. If I select that option, then go back to my application, I am able to connect to the host. Is there a way to programmatically tell iOS to use the connecting even though it does not have internet? I looked at the Zone property but that is read only. Here is the code I am using. Any assistance would be appreciated.
public async Task<WifiConfiguredEventArgs> ConnectToWifi()
{
try
{
var tobj_WifiManager = new NEHotspotConfigurationManager();
var tobj_SSIDs = await tobj_WifiManager.GetConfiguredSsidsAsync();
if (tobj_SSIDs != null && tobj_SSIDs.Contains(App.gvm_AppSettings.WifiSSID))
{
// We are already connected -- just return
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eAlreadyConnected;
}
else
{
var tobj_WifiConfig = new NEHotspotConfiguration(App.gvm_AppSettings.WifiSSID, App.gvm_AppSettings.WifiPassword, false);
tobj_WifiManager.ApplyConfiguration(tobj_WifiConfig, async (error) =>
{
if (error != null)
{
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eErrorEstablishingConnection;
lobj_WifiConfiguredEventArgs.ErrorMessage = error.ToString();
}
else
{
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eConnectionEstablished;
}
});
}
}
catch(Exception ex)
{
lobj_WifiConfiguredEventArgs.ConnectionStatus = FlexConnectionStatus.eErrorEstablishingConnection;
lobj_WifiConfiguredEventArgs.ErrorMessage = ex.Message;
lobj_WifiConfiguredEventArgs.ErrorException = ex;

return lobj_WifiConfiguredEventArgs;
}
}
Someone asked for the socket code so here it is. To be clear, the socket code connects and communicates fine in iOS when the access point has an internet connection. It also works fine in all the android calls.

I have no erros even if i remove try catch, i removed them from server and client and no errors...
Just took a quick look so not sure if this is the problem but you need to tell the program specific IP and ports to connect to when you're not testing on your own local system. You shouldn't need to worry about port forwarding as long as you are on the same subnet, but you should let the client know and server know what ports and addresses you want to use.

WebAPI call hangs when return a large amount of data

I have a web api call that I recently added to my app. I returns a complete list of all countries, states and cities in the app (currently 486 rows) I perform this call when all of the reference data for my application loads (I have a base loading page and call the function in my startup class to load all the data there). The challenge is that the call to get all my countries.... hangs and eventually I get "The operation was canceled" error. If I modify my stored procedure that selects the data from the database on the server to only return say 20 rows, it runs fine. Any suggestions?
Below is the code from the startup class:

So after much time, I believe I figured out what the problem is. The problem started to manifest itself again with smaller amounts of data and I could not figure out why. The problem appeared. The issue appears to be the IP address I was using. (I was using the IP address of the actual laptop I was hosting both the App and WebAPIs on.) It appears you have to use one of the other network adaptors for the emulator to have this work reliably.
Here are the steps I used to resolved this:
I launched my Windows 10 mobile emulator.
Click on the >> (Tools) icon in the tool bar of the emulator.
Click on the Network tab of the Additional Tools window.
Look in the list for the network adaptor labeled Desktop Adaptor #1 and copy the IP address.
Edit the Applicationhost.config file in the folder of the WebAPI project.
Find the entry in the file for site name="XXXXX" where XXXXX is the name of the Visual Studio project you are hosting your WebAPIs in.
Within the section of the entry for your WebAPI project, add a binding for the IP address you copied from in step 4. It should look something like this:
<binding protocol="http" bindingInformation="*:56952:169.254.69.220" />
Where 56952 is the port my IIS Express is hosting the WebAPIs on and 169.254.69.220 is the IP address I copied from step 4. After adding this, I was able to connect to locally hosted WebAPIs in IIS Express.
Hope this helps.

ColdFusion API using new http() and setMethod("POST") throwing 500 error

I have two ColdFusion sites in different servers.
I need to send a structure of an Agent (person) to be inserted in the other database server.
in the source server I wrote this code:
public Struct function addAgentToRemote(struct oAgent) {
local.stResult = {};
try {
myHttp = new http();
myHttp.setMethod("POST");
myHttp.setCharset("utf-8");
myHttp.setUrl(application.APIURL & "_com/API/agentAPI.cfc?method=addAgent");
myHttp.addParam(name="api_token", type="url", value=application.APIToken);
myHttp.addParam(name="agent", type="url", value=serializeJSON(arguments.oAgent));
local.stResult.data = myHttp.send().getPrefix();
} catch (Any excpt) {
local.stResult.success = false;
local.stResult.error = excpt;
}
return local.stResult;
}
In the destination server I wrote this code:
Remote String function addAgent(Required String api_token, Required String agent) {
local.stResult = newResult();
if (arguments.api_token NEQ application.APIToken) {
local.stResult.success = false;
local.stResult.error = "Wrong API Token...";
} else {
try {
agentDAO = new cfc.API.daos.agentDAO().init();
local.stResult = agentDAO.insertNewAgent(deserializeJSON(arguments.agent));
} catch (Any excpt) {
local.stResult.success = false;
local.stResult.error = excpt;
}
}
return serializeJSON(local.stResult);
}
I'm getting 500 error.
What is wrong ? My source or destination codes ?
Thanks.

I am using the OpenPop.dll and In the following code pop.getMessageCount is returning zero even there are mails in my account.
_Variable method contains all the variables I used in the code and in _MailReader. I am just reading all my mails from my application and returning into a list but this is the problem count is zero always.
It's a feature of gmail pop3 server. By default, you can receive only unread messages. That means, if you or somebody else already has downloaded certain message once, it will not be possible to receive it by pop3 protocol anymore.
To avoid it, you have to configure your gmail account. Check "Enable POP for all mail (event mail that's already been downloaded)" in "Forwarding and POP/IMAP" section of gmail settings.
