I'm using paypal sandbox to do some test payments and they have all been coming though fine until today. I'm not receiving an IPN from paypal and when I check in the IPN notification history all the messages are showing as Queued
If I resend an IPN that has a status of sent I receive that fine but none of the new ones are coming through.
I've checked my error logs on the server and I'm not getting any coding errors.
Am I doing something wrong or is this just a backlog on PayPals end?
Answer
I have the same problem - 2 years after the original post.
I wonder if this has to do with using a sandbox - and if it happens also in regular accounts.
I can get IPN messages using the simulator and event by asking the broken sandbox facilitator account to resent messages - all work find. It is just that new messages origincating from the broken sandbox facilitator account are endlessly queued.
I am quite certain given the evidence that this is NOT related to PayPal backlog.
My first messaged was queued 25 hours ago (and since it started I got plenty of messaged as resent IPN messaged + simulator messages).
ADDED: 3 days later, woke up thing morning to find out that suddenly all my queued messages in my IPN were served. Seems like they have some very slow process (humanized maybe?) that does solves the issue (identify stuck queues and get them running again). Once a queue is stuck, all following new messages get the QUEUE status until the nice PaylPal process get them running.
As indicated above, seems like all complaints are related to the sandbox accounts - this may mean that the process is much faster for non sandbox accounts or that the problem just does not occur in the real accounts.
