I've had that before and it's a very common error for me, actually. I can't say if this can help in your case, but I personally have found that I can avoid the error by only summoning after midnight for me.

So basically, although the day in the game changes at 5 p.m. for me, for some reason the FP daily summons follow my time. This means that I can only safely summon with FP after 7 hours from that, once midnight has passed for me. If I summon with FP anytime during that "danger period" I pretty much always end up getting this error.

So, if you're in a timezone where this may apply to you, try what I've done and you should be able to keep summoning without issue.
