Hello,
What on earth is this error? it seems to be related to access via a proxy server. I have set my application to use the system proxy and we've had firewall changes recently at work specifically the night before I experienced this so I'm quite sure this is somehow related.
System.Net.WebException: The operation has timed out
at System.Net.HttpWebRequest.GetResponse()
at Devolutions.RemoteDesktopManager.Business.WebBrowserManager.GetWebFileSize(String url)
How can I fix this or stop it from causing me delays. The application seems to hang for a while soon after launching an RDP connection after starting the application.
We call Business.WebBrowserManager.GetWebFileSize in two instances.
- Document session type where the file is a URL link
- Check for updates of our add-ons
Do you use any Document type sessions?
Best regards,
Stéfane Lavergne
No. I don't think I have any Document type sessions. Is there a way to check?
It never used to do this before.
Hello,
Could you post a print screen of your Help -> Diagnostic -> Data Source tab please.
This will indicate us if you have document entries.
Best regards,

Do you have the full stack trace of the error?

I've contacted support and according to them "hese errors are related to the KeepAlive feature of Devolutions Server". The problem is that I don't use Devolutions Server. I'm also on the latest release.
Indeed it's not related to the keep alive. In the latest version I have added an option No Internet Connection to avoid certain web calls. Could you give it a try? It's in File->Options

I've tried that option as well to no avail. Below is a screenshot showing the application not responding still!
The application log still shows:
System.Net.WebException: The operation has timed out
at System.Net.HttpWebRequest.GetResponse()
at Devolutions.RemoteDesktopManager.Business.WebBrowserManager.GetWebFileSize(String url)
Could you try to install Fiddler? It's a software to verify all the web called made by an application. I would like to know which called is made by the application.

I have made a fix that could help. I hope to release it later today.

Thanks. I'm glad to hear that. I'm disappointed with your official support team as I still haven't heard from them despite being under maintenance and support.
Your support on the forum has been great even though it's not the official support channel for customers under support.
Hi,
It's the same team but when we have an open topic on the forum, we use this channel since it would benefit more people.

Thanks for clarifying that. I'm working with my colleagues to allow connections through our firewall to your domains in the hope that that may fix the issue.
