Zapier not connecting with WordPress

Hi,
I’m trying to connect the Newspaper theme with zapier but I always get this error:

We hit an error when adding your new account
authentication failed: WordPress returned an error: Error code 406.

Make sure you click “Allow” or “Accept” on the permission popup
Double check your Account has the correct permissions
Check out our help docs for more information

The action I already took:
1. Deactivate Security Plugins
2. Check Remote Publishing Settings
3. Check Permalink Settings
4. Check role of the account – Author or higher
5. Deactivate Zapier/ Reinstall Zapier

I took all the basic actions recommended to fix this but nothing changed.
The plugins that are currently on are:
1.AppMySite
2. Cryptocurrency Widgets
3. LiteSpeed Cache
4. Site Kit od Google
5. tagDiv Cloud Library
6. tagDiv Composer
7. tagDiv Opt-In Builder
8. TranslatePress – Multilingual
9. Zapier for WordPress

What else can I do to tackle this problem?
I was connecting Zapier to other themes and it was super easy. Worked every time.
Please let me know what other actions can I take.

Thank you in advance
