I’m trying to login to a bank site that uses multi factor authentication. For security purposes, we’ll just use “bank” as a generic name. I receive a blank page when logging into the site.
Enter url of bank, press enter. “www.bank.com”
Homepage of bank loads without issue.
Select login, enter required information, enter.
Page changes to “www.bankonline.com/../../../mfa” (/…/… representing irrelevant path info), mfa being the multi factor authentication page.
Page loads as blank.
Why do I believe it’s the PiHole?
The site loads fine on the same devices and browsers on other networks.
Disabling pihole for 60 seconds allows the site to load normally.
I’ve tried checking logs, gravity.list and blacklist, the bank site does not show as being actively blocked.
My raspberry pi, pihole core, FTL, and web UI are all up to date. I’ve tried restarting pihole and rebooting the pi. I’ve tried whitelisting “www.bankonline.com” via web UI with no luck.
