NGINX error log - normal requests?

I am just looking at the nginx error log, and i can see some things that might be of concern. I don’t like the fact it is reporting a few errors.

I am particularly curious about errors such as:

seafile-server-latest/seahub/css/font/fontawesome-webfont.woff" failed (2: No such file or directory)

fontawesome-webfont.woff is under seafile-server-latest/seahub/media/css/font and not seafile-server-latest/seahub/css/font/ as the requested url.

Anyone else having these errors?
