Login page redirect loop on some subsites

We're having some login issues on our websites. We have Domain Mapping installed on our network and some of the subsites are having infinite login loops.
When you login, it just refreshes the login page. Sometimes it happens and sometimes it doesn’t, so it's kinda randomized it seems.

    Hello BrandCo

    I hope you are well today.

    I took a look at your site and noticed in Network Admin -> Settings -> Domain Mapping -> Mapped Domains tab that the 2 sites you shared with us in Live Support were configured like so:

    Mapped Domain: HTTP://domainname.com
    Original Domain: HTTPS://domainname.com

    This is what was causing the redirect loop. Login cookies are unique across HTTP and HTTPS, meaning the same cookie will not work for both by default.

    On those 2 sites, I changed the schema (by clicking the key icon in Domain Mapping) so that both the Mapped Domain and Original Domain used HTTPS://. As soon as I did this, I was able to login without issue on both sites.

    I hope this clarifies a bit. Let us know if you have any further questions. We'll be happy to help! :slight_smile:

    Best regards,

    James Morris
