I installed WP using WordOps and I can see in the nginx logs that it's blocking people who are using Facebook Messenger to share the article.
2020/07/19 17:00:12 [error] 44033#44033: *776504 access forbidden by rule, client: 18.104.22.168, server: domain.com, request: "GET /what-is-love/fb-messenger://share/?link=https%3A%2F%2Fwww.domain.com%2Fwhat-is-love%2F%3Futm_source%3Ddomain%26%23038%3Butm_medium%3Dessb%26%23038%3Butm_campaign%3Dmessenger HTTP/1.1", host: "www.domain.com"
How to fix this? Real users are getting blocked due to this? Where to change it.
