404 after update to 2.0.33 on Debian

[wilbert-vb]

2.0.32 was working fine on Debian with PostgreSQL and nginx.
After a recent update to 2.0.33 I get the 404 error.

Not sure how to troubleshoot this.

miniflux.conf:

# See https://miniflux.app/docs/configuration.html

BASE_URL=http://odroidxu4/miniflux/
FETCH_YOUTUBE_WATCHTIME=1
LISTEN_ADDR=192.168.1.253:8080
RUN_MIGRATIONS=1

nginx site-enabled/miniflux:

server {
    server_name     odroidxu4;
    listen          80;

    location /miniflux/ {
        proxy_pass http://192.168.1.253:8080/miniflux/;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

nginx access.log:
