Looks like my recent refactoring inadvertently added compression for the SAML POST binding. I’ve reverted that behaviour change in [FIX: Do not compress SAML request for POST binding (#55) · discourse/discourse-saml@792a51c · GitHub](https://github.com/discourse/discourse-saml/commit/792a51c9d1e93f4ee5e82244456478b71a1be276)

Please can you try updating the SAML plugin, and then see whether things are working better?
