Am I Experiencing A Phishing Attempt?

When attempting to launch the NextCloud app from my iPhone, I receive an official looking Helm log-in page that says “Please log in before granting iPhone Name (Nextcloud iOS) access to your Helm Account. If you are not trying to set up a new device or app, m someone is trying to trick your into granting them access to your data. In this case do not proceed and instead contact your system administrator.”

There is a “Log in” button and another link that says “Alternative log in using app token”

I am hoping the group can provide some guidance here.

FYI I am logged-in to my Helm / NextCloud server via my desktop computer, and all seems fine there.

Many thanks,

Dave
