No shared review access offsite

Hi Everyone,

I use shared review at work very frequently, and it functions exactly as expected.

However, when I leave the site and work from home via a vpn I am no longer able to set up a shared review, check for new comments on a shared review, or publish comments on a shared review.

I get the error message:

Could not get new comments. Adobe Acrobat cannot access the network. Please verify your computer's network connection and try again.

I have Adobe Acrobat DC (17.012.20098) installed.

The review server: unallocated.barefruit.co.uk

System is Windows 7.

All my other programs and software work fine, and I have full connectivity to the internet.

Does anyone have any suggestions for how to resolve this?

Thanks for any and all help.

All the best,

Charlie
