Hello there,
This can be caused by a number of things but is most often due to a long query string being sent in the URL but as this is only with specific devices please try the below steps.
-Check your server logs for mentions of the error or any other identifying entries.
-Your browser developer tools may give you some indication of the error’s cause — especially your Console.
-Reach out to the site owner or developer (if it’s not you) and let them know the error exists. It could be that they will have a fix or can advise you further on what to do.''
You can also Flush your DNS cache and see if that helps.,
Type 'ipconfig /flushdns' in the Command Prompt, and press Enter
Hope this resolves your Query !!
