I just upgraded to newest stable build of v1.17.2 and I no longer was getting any of the tickets from the fetching method. Looked furthur into it and found massive emails with the cron throwing errors:
PHP Parse error: syntax error, unexpected '=' in /var/www/hd/public_html/include/class.forms.php on line 4039
Line 4039: $config['size'] ??= $cfg->getMaxFileSize();
I went ahead and changed it to an isset statement and fixed all issues, (Yes old school way of doing it but works)
if (!isset($config['size'])) { $config['size'] = $cfg->getMaxFileSize(); }
