This is useful article. I'm getting following error when I tried to connect to Sandbox using Expressor:
Cannot establish connection, errorCode 1 message: "The response from Salesforce.com has incorrect structure. Please, check internet settings and date settings on your local computer. Code 1"
Please let me know .. did anyone faced issue and solution for the same.
Hi Ramesh, this is the message you'll get for any sort of a connection problem. The cause can be any missed step from the article. Try out the URL you're using from the WSDL in your browser, just log into your sandbox and manually enter the URL into your browser's address bar. If you're not getting back a slew of XML then you may have not copied the URL from the WSDL properly. If you're using an older version of Expressor you may need to change the API number at the end of the URL to an earlier version. It's also easy to select the wrong URL from the WSDL, so follow the instructions carefully!
Other causes could be an invalid token or password. Remember, unlike most other services that connect to Salesforce Expressor does not expect you to prepend your password onto your token, it wants the values separated.
Lastly, Expressor does provide a little help in troubleshooting connection issues with Salesforce. When you're in the process of configuring the Salesforce connection take note of the Test Connection button in the upper left corner of the user interface. Pressing that button tries connecting to Salesforce and will hopefully show you a more verbose error giving you the clue you need to better troubleshoot the issue.
