Failed to load resource: the server responded with a status of 504 (Gateway Time-out)

Hi all,   We have a critical misbehavior within a customer's production app. When executing a specific REST call activity, the app gives us the following error: - UI: displaying the dialog 'An error occurred, please contact your system administrator'. - Logs: but there is no entry within the logs. - Chrome browser: In the Developer tools console, the error 'Failed to load resource: the server responded with a status of 504 (Gateway Time-out)' is displayed. This misbehavior has been occurring in phases for three days, so there are times when it works and phases when it does not.   We could already exclude that the REST call itself is faulty and we could exclude that the receiver is not reachable. This concerns all three environments of the customer (TEST, ACCP, PROD) and in fact (so far) only this one REST call.   If I restart the apps on the test and on the prod environment, then it works again. This behavior, that after a restart of the app the REST call works again, we already had yesterday. What could be the technical reason for this? Environments: Private Cloud (MS Azure) Studio Pro Version: 8.18.24

Hi Max, I had a similar issue a while back. A lot of data was displayed on screen. It turned out that in the logic that retrieved the information (datasource microflows, listview in listview) had one refresh client activity too many. Removing that solved the issue.
Some users had more issues than others which lead us to think it was related to the client/browser specs.
