An infinite number. That's not enough to go on. Address issues, cookie issues, network timeouts, a million things.

Lots and lots of tracing of traffic and direct observation. It's generally never done so there are no follow ups to to these sorts of questions and I have no idea what to tell anybody about it.

The recent thread on the IdP and replay errors is an example where there was at least some follow up to understand what was going on and what might be done about it. You'll find a thousand threads on "timeouts" in the archive that purport to claim things don't work right for some situation and the end result is either no response or finding out it was misconfigured in some way. There's never any real explanation of what the issues were.
