I have a flow with more than one approval level. Approvers' information comes from filling out an external form (Nintex Forms). When I fill with two emails the flow runs correctly, but when I select a group with seven people, it fails. I've already checked that all users have the required license, as the stream doesn't fail at runtime, but after a few minutes. And it's not a temporary error. The error that the system reports is the following: "The request failed. Error code: '504'. Error Message: 'BadGateway'.". Please do you know what might be going on?
