Hi Team,

We're getting 503 Service Unavailable error as a JSON Response for the below API calls for my clients. Please ping me for Client details. API Response as below.

This problem started at about 4:15 AEST. So over 4 hours ago.

We try three types of downloads and 2 types of uploads, and use Webhooks to initiate the downloads.

Webhooks are working correctly - and responding them works most of the time (maybe 1 in 100 result in a 503 error).

Once the webhook has been processed, subsequent Job downloads work intermittently - and seems to depend which company is downloading. Some work all the time, some work sometimes and some never work.

For Uploads..

Uploading PDF attachments to jobs works every time
Uploading line item details and materials etc into Jobs never works.

In addition - ad-hoc functions like connecting to simPRO API, or reading details about the customer/company fail 95% of the time.

Can we have an update please? We have suggested to all of our customers to raise support requests with simPRO using the helpdesk, although they know we have also done so.

Thanks
