Thank you so much for your help!!
I worked through this last night, and still had no luck. Here’s the current URI: https://scscmoscow.com/wp-admin/admin.php?page=forminator-integrations&slug=googlesheet§ion=authorize&global_id=67e4e4a6da9cb6.14405621
I searched about unblocking ajax, and I read about ModSecurity. I tried turning that off, but that didn’t help either. I also read that it could be an issue with cache, so I turned off LiteSpeed Cache. No luck there. I do have WordPress Security and Wordfence installed on my website as well. I’m going to try turning those off and see if this works. On my computer, I do have CloudflareVPN turned on. I tried it with the vpn turned off, and still had the same issues. I did look through the cpanel, and other than ModSecurity, I couldn’t find anything else that would possibly change ajax.
