Hi @Iman, welcome to the ODK forum! We're glad you're here. When you get a chance, please introduce yourself on this forum thread. I'd also encourage you to add a picture as your avatar because it helps build community!
Is there a reason you are installing Aggregate and not Central? Please note that Aggregate is no longer being supported. Central is now the ODK server. We strongly recommend using Central becauseAggregate has not been patched for security, reliability, and other issues since May 2021 when it reached end-of-life. The post below has more details.
