Hi, This site:
www.centrumvoorurologie.nl
is based on Gantry (v4.1.34) and RT_Acacia template (version 1.11) and Joomla 3.8.2. The sites uses SSL/HTTPS.
Off course, the url's avobe point to non-existing pages.
This happens intermittently and sometimes even occurs when you refresh a page. Also from wrong url's to correct url's when you refresh the page (Ctrl-R). This happens only at url's from menu-items, never on url-links in text, modules etc. And both from the Main-menu at the top, as the website-menu at the bottom.
Can this problem be caused by your extension RokNavMenu? Where should I look for solving this strange problem? I've checked:
.htaccess
Cache-extensions
PHP-settings
System Check from RS!Firewall
Completely reinstalled Joomla!CMS from a install-package (Copied all Joomla-files over the existing files)
The site is very good secured by 2FA, RS!Firewall, Admintools, etc. I've never seen this in other Joomla-sites...

Are you using a CDN? (e.g. cloudflare) that go do things like this so turn it off
Turn off "system - page cache plugin" and clear server cache.
Does clearing cache resolve the issue?
It won't be caused by roknavmenu. It good be htaccess but I doubt it. It's more likely a caching issue or possible a SEF extension (e.g. sh404sef?).
Make sure everything is on the latest versions too.
Regards, Mark.
