I am having some issues trying to make an AIR application connect to a RemoteObject when the application is run in a domain that has proxy servers for outbound connection.
The error provided is as below:
[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Failed: url: 'http://myTestService.org:8080/default/message/amf'"]
Any ideas? I think the proxy server may be preventing the application from accessing the Remote Object. How do I work around this?
Thanks.
Edit:
I saw a quite similar post to this:
Remoting with AIR
And I did declared the endpoint and destination to my RemoteObject.
In application/WEB-INF/flex/services-config.xml give only relative paths, do not use ip address and port number. You can look here for detail moving to production server
And here send failed error
In your case channel url should be
"/default/message/amf"
Drupal RPC Fault looks to be some what same as your problem and has issues with crossdomain.xml
Do check it.

I have created a mule application with client_id and client_secret, TLS keystore and deployed on cloudhub. I am able to run application locally but cannot run with cloudhub url.
URL: https://system.us-e2.cloudhub.io/api/refund with PUT method with json body.
It is throwing '405 Not Allowed'
Thanks in advance
Probably you are not pointing to the right application. The error is coming from CloudHub load balancer, indicating that it didn't reach your application. Check that the URL used is the right one for the application. Also that the application is listening in the right port. For CloudHub an HTTPS listening application has to listen in port 8082.
You can try to troubleshoot by contacting directly the application's worker. For example: https://mule-worker-system.us-e2.cloudhub.io/api/refund:8082/...
Your application should have an HTTP Listener configuration like:
<http:listener-connection host="0.0.0.0" port="8082" protocol="HTTPS">
<tls:context>
<tls:trust-store path="keystore.jks" password="123456"/>
</tls:context>
</http:listener-connection>
Note that in this configuration the port used is "8082".
A client is running our C# gRPC client on a corporate network, behind an HTTP proxy. The http_proxy environment variable is configured, but nevertheless he sees an error message Name resolution failure when attempting to connect to the server on the internet.
DNS resolution from the same machine works fine using nslookup.
Any ideas what I can do to investigate this problem?
You can use the following three lines at application startup to configure the detailed logging that #JanTattermusch suggested:
Environment.SetEnvironmentVariable("GRPC_TRACE", "api");
Environment.SetEnvironmentVariable("GRPC_VERBOSITY", "debug");
Grpc.Core.GrpcEnvironment.SetLogger(new Grpc.Core.Logging.ConsoleLogger());
In order to connect a C# gRPC client on a corporate network, behind an HTTP proxy, add this on the client main method works:
Environment.SetEnvironmentVariable("NO_PROXY", "127.0.0.1");
I'm trying to import all my stuff from videomarathon.com/dk to videomarathon.com/se (posts etc.)
I'm using wordpress importer.
When uploading the exported file, it shows me this error:
Error 503 Service Unavailable
Service Unavailable

Does anyone know what it means?
Is there anyone who might know another plugin for importing?
I'm using multiple sites, so maybe that's an issue?!
Thanks!
HTTP Error 503 - Service unavailable
The Web server (running the Web site) is currently unable to handle the HTTP request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. Some servers in this state may also simply refuse the socket connection, in which case a different error may be generated because the socket creation timed out.
503 errors in the HTTP cycle
Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server:
Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
Open an IP socket connection to that IP address.
Write an HTTP data stream through that socket.
Receive an HTTP data stream back from the Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.
This error occurs in the final step above when the client receives an HTTP status code that it recognises as '503'.
Fixing 503 errors
The Web server is effectively 'closed for repair'. It is still functioning minimally because it can at least respond with a 503 status code, but full service is impossible i.e. the Web site is simply unavailable. There are a myriad possible reasons for this, but generally it is because of some human intervention by the operators of the Web server machine. You can usually expect that someone is working on the problem, and normal service will resume as soon as possible.
Please contact the system operators of the Web site (e.g. your ISP) to determine why the service is down. They will be in a much better position to help you than we are for this type of error.
Talk to your web host; it's an error at your web host one.com. The WP import plugin will work fine once the host problems are fixed.

I am using a Socket (not xmlSocket) connection between flex applications and the server pushing messages.
Now, when I connect from the local machine to the server everything is working file and running, connection is succesful and I get data back and forth.
When I upload the application (flex) to the server and run it from there, I get a security sandBox violation message.
Note:
1. I do have a crossdomain file with * wildcard both on port and on domain.
2. I created a Securiy.allowDomain("*") as well.
Another thing.
I also created another listener on that same server, listening to connections for port 843 (default) and this service just waited for a connection send policy file to the client and that's it.
That did not solve the problem as well...
That's next?
What should I do to fix the problem?
Appreciate your help.

The fix for this issue was a dedicated policy file serving server.
I implemented a socket listening to the dedicated port where flex is looking for policy file, once I got a connection and a request I answered right back with the appropriate policy file.
This solved the problem for all users and is working very well for me.
Thanks
did you try Security.loadPolicyFile? Does your server on port ever actually 843 receive policy file requests (that's a tiny XML sent to request the crossdomain policy file)? Does your actual server ever receive policy file requests? What traffic do you get on your server?

Add crossdomain.xml to your Web server root directory, for example,
C:\inetpub\wwwroot.
Java
Add crossdomain.xml to \ArcGIS\java\web_output, for example,
C:\Program Files\ArcGIS\java\web_output.

I am going to develop a http service and an application as its client which both of them are in the same computer.
I have 2 questions :
Might any firewall block this application?
If so, how can i solve the problem?
Tanx in advance.
No the firewall will not block the application.
You can use 127.0.0.1:80 to access the local http service. 80 is the default port number and you can drop it. Alternatively, you can use something like http://localhost to test it.
