Is it maybe because of physical distance? How far is your VPS from the Backblaze region? Check the bucket “S3 Region”. I’m stuck on west, for example, even though I live on the other side of the country. There’s a way to switch, but I haven’t had the need to bother with it.
Vanilla nginx is still too far over my head, but Nginx Proxy Manager makes easy work of it.
A lot of people like Caddy but I’ve never tried it. The config files are much simpler and it auto-renews certificates (but so does Nginx Proxy Manager).
