Hello, exact same problem here.
When signing in, client gets a "Too many redirects, Try again" (this is the wording on Firefox, but I have tried Chrome and Edge, same problem) error.
Then, I've experienced both of the following:
a) no matter how many times you press the "Try again" button nothing new happens
b) after pressing the "Try again button" (maybe more than once) you get to your account page
But always, if you press the "Back" button of your browser, you land on the previous page but signed in.
My setup:
Prestashop 1.7.5.2, default theme.
Shop parameters > General: SSL enable: YES, Enable SSL on all pages: YES
Shop parameters > Traffic & SEO: Shop domain: www.panacea3.gr, SSL domain: www.panacea3.gr, Base URI: /eshop/
Any news on this?
