Hello Limesurvey community!

I've been working with a nonprofit for 3 months to design a survey that will save them the struggle of writing everything on paper and then typing it in a spreadsheet. Limesurvey is perfect for that and the design is easy.
After deploying limesurvey on our own internal server with a VPN (access is at a static ip adress), the import in Offline Survey with a TUN VPN activated worked perfectly.

This week we finished the final version of the survey but the import in Offline Survey doesn't work.
"Checking internet availability"


After a while it states :
"Error: Internet Unavailable"


I have no idea where this error is coming from. I've learnt by heart the prerequisite settings and common errors from the Offline Survey website (and it used to work fine!).

I've noticed something interesting though:

• Start the import with VPN paused
• Activate the VPN while it's checking the survey URL
• And this is what I get: it loads and displays the survey in a modal
  
  

Is there anyone here who would know what is happening here and where does it get stuck :dry: ?

PS: I'd like to thank all the contributors to this great project and the community for the really helpful threads on this forums (that were really useful many times already!).

Hi we need internet while adding a new survey and syncing responses to connect to our remote Firebase Back-end (for licensing and security purposes)

I'm a newbie here. I also want to be part of the survey through VPN. Which VPN are you using?
