Web Setup Wizard not reachable with varnish caching active

[andidhouse]

Magento 2.0.6
Varnish installed version 4.2

Configuration made according to magento guideline.

Problem:
When clicking on the Web Wizard from the backend the site gets redirected to:

http://www.domain.com:8080/setup/

And a blank white screen is shown.
When reloading the site we get redirected to http://www.domain.com:8080/setup/index.php/session/unlogin with this message:

Hi @afavata
Is this issue still reproduces?
Please try to clean varnish cache, or restart varnish process

Hi @oshmyheliuk

Yes.... issue is still reproduced.
The only way to upgrade is by command line.
No way to access to the Web setup wizard

Thank you

Hi, guys!

Cannot reproduce it.
Do you have the same issue on Magento 2.0.10?
Please, provide information about your environment (php, web server, OS, etc).
