Lansweeper Server not able to pull Client Information from Relay Server

[Ansgar]

Hey Community, 

we want to use the Lansweeper Relay for the Agent communication. We can see in the client logs that the client connects to the Relay and sends the package successfully. However the Lansweeper Server is not able to pull the Information from the Relay Server. In the Relay Configuration of the Server everything seems ok. IT has a green checkmark and states "LSAgent access granted".

The Client are not appearing in the Inventory and the Server Error log shows the following:

2024-07-31 23:56:14,658 [235] ERROR could not sync asset scans from Relay

Does anyone have an idea what the issue can be?

Thanks

Dear, 
Please check if the requirements are met in the KB article below, to make sure the requirements are met. 
The relay could not be contacted - Lansweeper Community
If issues remain, please contact Lansweeper Support, they should be able to help you further based on the logfiles from your scanning server.

Thanks Frank. I checked the article. This is not the error we are facing. The relay service is able to connect (see screenshot). It is just not downloading the client information from the relay. I opened a Support Case.
