Are you using phantomjscloud or are you running PhantomJS locally?
Also, does the link in the error work for you in the browser when you’re logged out? If you require clients to enter a password you’ll need to set a value for PHANTOMJS_SECRET in the .env file.
What i see is that it used to work great but sudeenly it stopped.
I saw after search in a previous topic that its because of the https that we have the source of the problem.
Do you think that it might be it ?
Problem solved.
It was a missconfiguration in the .env file.
I have moved my setup in a new domain a few weeks ago and one of the variables in the .env file had the old domain.
