    The dreaded:
    This occurs sometimes on 1st page load of a site, a number of the images will fail to load.

    Looking in developer tools in Chrome we see the quic error. Which seemingly results in the full image data not being sent in response:

    Response header says:
    accept-ranges bytes
    alt-svc quic=":443"; ma=2592000; v="35,37,38,39"
    cache-control public, max-age=31536000
    content-length 425391
    content-type image/jpeg

    strict-transport-security max-age=31536000
    x-content-type-options nosniff
    x-frame-options sameorigin
    The content actually returned is 0 bytes. This is confirmed by the server log:
    <snip? - - [31/Jan/2018:09:42:26 +0000] "GET <snip>1372326053.jpg HTTP/1.1" 206 0 "https://<snip>/" "Mozilla/5.0 (Linux; Android 6.0.1; FP2 Build/FP2-gms-17.12.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.111 Mobile Safari/537.36"
    Response is served to browser as:
    We've also seen partial sends as well as 0 byte sends.

    Looking in the error log we see nothing related to that request.

    Please try upgrading to 5.2.4 which was released yesterday. In the later builds of 5.2.3 we fixed multiple QUIC issues like you describe here.

    You can upgrade with the following:
    /usr/local/lsws/admin/misc/lsup.sh -f -v 5.2.4
