Suddenly Facebook Open Graph issues
-
Hello
I’ve been using Yoast for years and never had any issues with FB open graphs. Now suddenly, I have the following warnings with the Problem, that my chosen Facebook image does not work anymore. This applies to all posts and even the older ones that worked some weeks ago with no issues:
Curl Error
Curl error: 61 (BAD_CONTENT_ENCODING)
Inferred PropertyThe ‘og:image’ property should be explicitly provided, even if a value can be inferred from other tags.
Missing PropertiesThe following required properties are missing: og:url, og:type, og:title, og:image, og:description, fb:app_id
Thanks for your help

Hi,
We then checked the URL https://www.alle-schweizer-wettbewerbe.ch/fitbit-versa-lite-gewinnen/ and we can see we are outputting the right og tags. See image: https://ibb.co/qkYnpgk
We also used the Facebook Debugger here and we see that curl 61 error.
It seems that there is something in the way your server is sending the content to Facebook that is causing this error and preventing the right data on the page to load. As a result Facebook is just using cached content to show when you share the URL.
Possible Solutions:
1. Doing some research, we’ve found some reports that enabling GZIP compression can cause this, but we cannot say if this is the case on your site. See: https://stackoverflow.com/questions/25405457/facebook-open-graph-required-property-ogtitle-of-type-string-was-not-provi.
We recommend contacting your webhosting provider with these details, they should be able to provide you with additional information.
2. If you are using Sucuri there is a setting called “Enable Emergency DDOS protection,” which blocks the site from any browser with JS disabled (except major searchbots). It could toss out that warning. This guide explains more: https://docs.sucuri.net/website-firewall/configuration/security-options/.
If you are not using Sucuri you may want to check with your host provider or other security plugin authors to make sure there is nothing about the configuration that could case it. They may have a similar feature enabled.
We’re not using Yoast so take this with a grain of salt. But I thought it important to share. Facebook appears to require compression. Here are their requirements:

Once enabled the FB OG debugger started reporting success. We edited our htaccess directly for this.
