Sharing Product Link in Facebook Messenger Shows Bad Request

When I share any product url in facebook messenger it shows bad request. My websites default language is Bulgarian.

Product Link: https://magnumopus.bg/%D1%80%D0%B5%D0%BC%D0%B1%D1%80%D0%B0%D0%BD%D0%B4-%D0%B2%D0%B0%D0%BD-%D1%80%D0%B5%D0%B9%D0%BD-%D0%BD%D0%BE%D1%89%D0%BD%D0%B0-%D1%81%D1%82%D1%80%D0%B0%D0%B6%D0%B0-1642-1649

Can anyone please tell me what I need to do for resolving this issue?

Thanks

What nopCommerce version? Something similar has been discussed here.

@RomanovM Thanks for your reply.
I am using nopCommerce version 4.60.5

I checked your reference post. All settings are already checked. Still getting the bad request when sharing the product link to facebook messenger.

Perhaps user-agents of Facebook Messenger are recognized by your server as unwanted bots, so it blocks them and returns a Bad Request in the preview instead of the actual page.
