There are 3 reasons why there might be a timeout error.
Follow these steps below to troubleshoot:
Reason 1. Your Facebook account is still on the old Facebook layout
FriendFilter no longer works with the old Facebook layout
So if your profile image on your profile page is on the left and not in the center
Please update to the new Facebook layout
Reason 2. Connectivity to Facebook
FriendFilter works on your local machine
Meaning, FriendFilter servers never detect your information on your page from our servers
So your internet connectivity is vital to receiving the data from your scans
If your internet connection is slow, or connection drops the app will error
Be sure to have a strong internet connection when running FriendFilter
Also, if your internet connection is strong, Facebook connection to your IP address needs to be strong
If you are having issues connecting to Facebook with a strong connection, just try again later.
Reason 3. Unstable scanning going back too far in your timeline
As the app scrolls back to find previous data, Facebook connection could timeout
Meaning, Facebook times out the page if you try to scroll back too many posts
Some users post to Facebook multiple times per day, and after X scans Facebook could time out the page
This is outside our control, although we are constantly improving the stability of far-back scanning
If you encounter this issue with scanning back 100's of posts back and then an error occurs
Just change your days to fetch to a smaller number: https://app.friendfilter.io/settings
Note: Once you scan back old posts, there is no reason to scan those posts again.
FriendFilter already has that data, so it is a best practice to change the scan back days to the smallest number
For example: If you set your scans to 14 days, then just scan every 2 weeks to keep data updated
