what is vpn for real
CMS cannot connect, but with a browser, I can.
LOG at first looks good. But when working with CMS, logging could be extended with "some" details
--- It shows you how many warnings and errors you have. But you have to use "filter" to see them
--- General error in the log is a very specific issue. why not write the specific issue to the log? (Photo station also need PHP7 and dependent packages are not automatic with CMS)
--- I seem not to be able to get the Policies working. but there is also no line at all on the policies in the log. So, how to troubleshoot?
