Android Amazon Web Services Unable to execute HTTP request: sdb.amazonaws.com

Question

I have been getting the following errors when saving to the amazon SimpleDB.

My code (taken from amazon tutorial):

Account.getSimpleDB().createDomain(new CreateDomainRequest(Account.getDomain()));

The Account class methods (getSimpleDB() and getDomain() I've tested and work. The problem is most certainly taking place in the amazon methods of createDomain() or CreateDomainRequest()

The Errors:

What is very strange to me is that sometimes I run the code it works, but other times, it doesn't. It seems maybe that if I change wireless networks then it stops working, though I am not sure about that theory. I have tested the code on my actual phone and never found an issue, but running it on my 2.3.3 emulator sometimes I get the following errors... but not always. Lastly, I do have the INTERNET android permission and I do currently have a working wireless connection.

Any ideas? Thanks in advance...

In your client configuration, if your service is regional, I think you need to set the endpoint desired. Did you set the end point ?
