BASE_URL stopped working

[fallenleavesgocrunch]

The BASE_URL environment variable used to allow subpathing, eg:
BASE_URL=https://myserver/dumbkan

But now it will only respond to / not /dumbkan

wget http://localhost/dumbkan/
response code: 404

wget http://localhost/
response code: 200

Did you just update? Last update was 16 days ago so shouldn't have anything in the last few days that would break it.
