Actual Behaviour:

Rather than asking for password, I get:
Secure Connection Failed

An error occurred during a connection to pi.hole. SSL received a record that exceeded the maximum permissible length.

Debug Token:

token is: https://tricorder.pi-hole.net/WIUnJsBA/

Actions taken:

Error started after doing: pihole -up

Rebooted system and changed browsers, same error

You are using FTL development.

This version has some changes related to SSL and I think it is probably causing some incompatibility, specially if used with Core and Web master branches.

Try to use the current FTL release if this command:

sudo pihole checkout ftl master

Does this fix the issue?
