[TYPO3-english] typo3 8.7.8 / 7.6.23 SSL backend missing parts

[Christian Zoffoli]

Hi to all,
I've a setup based on nginx SSL only. After updating to 7.6.23 I cannot see the right part in the backend ...so I cannot edit anything.
I can see only menu and the tree.

I've tried to update to 8.7.8 and I've the same problem.

If I switch all to HTTP I can see everything. I've seen similar bugs in your bugzilla but I've not found a solution for my setup

Do you have any hints?
