Hello

I've noticed a few of the the xml api endpoints seem to return 221 errors (illegal page request, check permissions) at random times despite the permissions being set correctly, even if you have properly set rate limits and honor the cache timers. It's especially annoying since these errors have a 24 hr cache meaning you won't be able to access any data for a day until it's refreshed unless you force another request/ignore the timer (which always seems to work and returns valid data but I don't think CCP likes this).

Does anyone else have this issue, or have any ideas on how I can solve it? It seems to happen with just about any endpoint at random times for no apparent reason.

Been happening for years:

I ended up patching my code to not trust 221's, since phealng already checks the access mask on the key up front so it's unlikely to be legitimate unless someone's revoked specific access and it's not picked up the change yet, and instead I treat them as false transient errors and retry in an hour - not accepting the 24 hour cache.
