Topic: Warning in Unity console "Couldn't connect to server"

Hi,

I just started a project I was working on a few months ago, and I noticed the following warning message showing up in the Unity editor console:

Console wrote:

The maps load, and everything seems to be fine at first glance, though. Doesn't matter if I use Google, Bing, Here...  I also updated to the latest stable version which as of today seems to be 2.5.13.1.

What does the message mean, is there something I can/should do about it?

Hello.

[OnlineMapsTileSetControl.cs:955] OnlineMapsTileSetControl:OnElevationRequestComplete (string)

This line means that you have some problems with connecting to Bing Maps Elevation API.
I checked the work of elevations on my side, and it works correctly.
Unfortunately, I do not know why this problem is happening on your side.
There can be many reasons why this is happens.

Re: Warning in Unity console "Couldn't connect to server"

Right, I noticed the elevation data didn't work anymore. I have no idea why, though. The key didn't expire, I even tried creating a new one, also doesn't work. Usage report on bingmapsportal.com doesn't show any access attempts for the key. I think I remember there was a documentation with a few things to consider, but I cannot find it anymore. The documentation PDF doesn't tell much... I have to set the provider to "Virtual Earth (Bing Maps)", right? What else can be wrong, is there a way to isolate the source of the issue? I tried to check the "Use Elevation" check in the Tileset sample and enter the key -- also doesn't work, however I remember this was quite straightforward in the past. I am not sure, maybe I got some bad configuration of my assets, but I cannot think of anything that's changed as I didn't touch the project for three months or so.

Re: Warning in Unity console "Couldn't connect to server"

Provider of tiles does not matter.

How to isolate the problem:
1. Try to make a request to Bing Maps Elevation API using OnlineMapsBingMapsElevation.GetElevationByBounds.
http://infinity-code.com/doxygen/online … a5e824decb
2. Try to make the request using WWW like in example from MSDN:
https://msdn.microsoft.com/en-us/library/jj158961.aspx

If the problem persists, you can use ESRI Elevations instead of Bing Maps Elevations.
Example:

Re: Warning in Unity console "Couldn't connect to server"

Hi Alex,
Thanks for the reply. I tested 1) and got the same error (Couldn't connect to server). With 2), when I'm requesting 

http://dev.virtualearth.net/REST/v1/Elevation/List?points=35.89431,-110.72522,35.89393,-110.72578,35.89374,-110.72606,35.89337,-110.72662&key=BingMapsKey

with my BingMaps key inserted at the end, I'm getting the following response: 

<html>
<head>
<script>window.close();</script></head>
<body>
<img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7">
</body>
</html>

Not sure what that's supposed to tell me. Maybe somebody can give me a hint. ESRI works so far, thanks for the hint!

Hello.

<script>window.close();</script>

This is a very interesting line.
Do you have any corporate or personal proxy?
It looks like your request has been blocked from the outside.

Re: Warning in Unity console "Couldn't connect to server"

Jesus! You were right, there was a misconfigured DNS adblocker installed by our IT guys, listing the domain site as ad/scam. I actually expected getting something like an HTTP error code in such a case...

Works again, thanks!
