CAWI: cannot distribute survey

After I set up my API key using SendGrid, I still cannot send an invitation or retrieve the link. The message shown as below.

" Invitations
0 total invitations.
No invitations have been sent yet.
No invitations to send as of now.

Web survey has been started and email provider was set up properly. The system is ready to send invitations."

However, I cannot click “send invitation” so I wonder where and how can I set the invitation or emails to send?

Thank you very much in advance for your support.

If you create a new web-assignment with a valid email NOW, after setting up the sender, will it let you send an invitation?

I tried putting 1 email and the email to start the survey was sent to me. However, when I click “start interview”, the page doesn’t work. It shown as below.

This site can’t be reached

localhost refused to connect.



Kindly advise. Thank you!

Have you changed your BaseUrl as stated here Server Installation ?

Does your link start with http://localhost:9700/?

Yes, the link starts exactly like this.


when configuring the application, what address have you written in the BaseURL setting?

(See: Survey Solutions application configurationBase URL)

Generally this happens when the service running on your localhost has some problem resolving the request. If you have access to logs, please see logs for more details on the error. Also, make sure the application interface, server, and services are running. There are many situations that might trigger “this site can’t be reached” error in browsers. Sometimes the server is still running but the interface application is closed or the database is down. If your application interface and server is up but a dependent service is down then restart your computer/server and restart services. Make sure the app is bound to localhost. It may just be bound to an individual interface. netstat -na will give you the clues you need. Run a port scan on your computer and make sure the port is opened.

The problem may happens for failing on DNS lookup . DNS is that network address that translates the website name to its internet address. Most often it causes for not getting the internet connection or misconfigured internet or network settings. Another reason could be the firewall preventing Google Chrome to load the webpage. However, other reasons, such as insufficient permissions or the Apache web server not running properly might also cause the error.

I believe the post by bradmacer is a repost from other forums dedicated to other software (for example the same text can be found here: This site can’t be reached - Browser Feedback - Brave Community and here: HCL Notes/Domino - Verse Forum? - Community and possibly in other sites).

The advice by bradmacer is diverting the attention from the actual problem (baseURL not specified in the Survey Solutions configuration) into some general internet functioning problems. It is also disregarding the fact that the message specifically mentions localhost, which is a special site name, and hence the advice makes even less sense.

@rapidasia, has the issue been resolved by modifying the BaseURL setting?
