When I try to log into my Instagram account via Facebook (on a laptop) I keep getting "sorry an unknown error occurred, please try again". I've reset passwords, tried different browsers, cleared caches, etc., and still no connection.
However Instagram does connect to my FB account from my Android phone and has found all my friends to follow, etc.
Does anyone know how to fix this problem?

A lot of times ad blockers and privacy guards block connections from one domain to another.
It might lead to failures in connecting to one service using another.
Try check what the ad blocker / privacy guard has blocked, and also check the console logs. If you see that something related to facebook login/connection was blocked - it's probably the reason.
