Strange problem: www.ads-software.com plugin search error only certain words

So I was just about to install “Titan Framework” and I go to the “Add Plugins” page as usual. However, when I try to search for “titan” I get the error:

An unexpected error occurred. Something may be wrong with www.ads-software.com or this server’s configuration. If you continue to have problems, please try the support forums.

If I search for “options” or “framework” the search works fine.

So, I tried the following steps:

• Disabled all plugins.
• Changed to default 2017 theme.
• Altered wp-includes/class-http.php and set timeout to “15”.
• Reset server PC
• Reloaded Xampp

I have wordpress running locally on XAMPP on port 800 (not 80). I’ve never had this problem in all the sites I’ve done so this is weird.

Is this perhaps just a search bug and it’s not finding the word “titan” or something?
