One of my users is unable to log in. He’s getting the error “You can’t log in as _username_ from that IP address” (where _username_ is his actual username). I’ve whitelisted `148.64.0.0/21`, which should match his public IP. It’s 148.64.2.45, according to google. Here’s my Screened IPs config:

Any ideas why this person is being blocked? What else can I do to troubleshoot this?

Looks correct to me.. are IP addresses not correctly sent to the app via unusual proxy/routing config? What happens when you test this by adding a test IP to the block list, then logging in from that IP?

It turns out that due to using AWS CloudFront, discourse sees all users as having an IP address belonging to AWS CF.
