Failed to get available update data for 38 projects.

I've been playing with D8 and thought that the failure to fetch updates was something in D8
but it appears that it might be my server.
when I went to make changes to a D7 on the same server I can't confirm the versions I am running.
I am running a linux server with nginx
I noticed nginx has update to 1.8 from 1.6 so am guessing my nginx conf is part of the issue however it is very minimal and I really have no idea why this would suddenly happen and I have tried googling and looking around on the forum I couldn't really see anything that sees to have help I have tried clearing the cache and checking that .hcaccess is present.

server block info below:

server {
client_max_body_size 20M;
listen 80;
server_name xxxxxxxxxxxxxxxxxxxx;
root xxxxxxxxxxxxxxxxxxxxx;
location / {
index index.html index.htm index.php;
error_page 404 = @drupal;
}

location @drupal { rewrite ^(.*)$ /index.php?q=$1 last; }

location ~ \.php$ {
fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
}

Sorry if this is wrong place for this my first issue listing.
