Problem
The report loads, but stops, and an error appears, or it does not return all data. If smalled report is generated, it returns ok.
Solution
It's possible that the report is failing after exactly 1 minute or 60000ms; in this case, there is a limitation in the request time in some network settings. It's usually in the data center load balancer, but it can also be in Jira settings or a specific network setting.
