Strange redirects

Hi

I get some wheird logs on my system

"GET /wp-content/uploads/2007/12/05.JPG HTTP/1.1" 301 185 "http://aaaaa.bbbb.cc/subpage" "Mozilla/5.0 (Windows NT 5.1; rv:51.0) Gecko/20100101 Firefox/51.0"
"GET http://www.xxxx/ HTTP/1.1" 301 185 "http://www.xxxx/" "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)"

While 2-nd might be acceptable 1-st does not look right...

I do not have such file on filesystem...

Here s my site config
https://paste.ngx.cc/7c

NGINX version -> 1.10.2

Let me know if additional information is needed?
