It seems that you r website is not allowed to access files outside your server.
The scripts to load files from outside your server all time-out.
The sun script fails as a PHP function is not defined, first time I see that
Fatal error: Call to undefined function gregoriantojd() in /web/maui/swanston/htdocs/pwsWD/sun_block.php on line 7
It is a standard PHP function for versions 4 to 7.2 but the provider should enable that (most do)
http://php.net/manual/en/calendar.installation.php
To get these functions to work, you have to compile PHP with --enable-calendar .Wim
