FYI
I tested without the filter, but it does not change the loading time.
What I do see is:
1. Avada -> fusion pagebuider: opening/saving the page with view shortcode is running the code also in the back end. So this edit page is also slow. Why is code being rendered in the page edit (wp-admin)?
2. The first 21 calls on the nominatim url are status 200 OK, after that they are 429 too many requests.
Can you please send me admin access details and let me check couple of things.

I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
That is strange. There are no restrictions and you are admin user.. When I check this it just works fine.
Is this your ip address? xx.xxx.156.161? Then it could be the application firewall. If so I will switch it off.
