Network connection issue

[Alaminkhan907]

Hello, i am using two raspberry pi 4b one as controller(linux ububtu 24 installed) and another one installed with eve os.
This setup is installed in university network(eduroam).

Now the error i am getting is which make me confused. when i installed eve and connect with eden it's work fine. and i keep it run for overnight . next day or day after next day when i go to university lab , i found that eden cannot found eve.if i try to onboard again . try to establish connection several time and finally not success.i have very little idea about networking i didn't get any clue. i am using all latest version of EVE-OS , EDEN .

Important to mention , i have setup same configuration with mac mini 1 with raspberry pi 400 when i connect mac mini and raspberry directly with cable and mac mini share network through cable and work as router . In this connecting everything working perfectly . However , in this connection i am not using . university (eduroam) network.

I am expecting your valuable suggestion . I will be grateful . Thank in advance

@Alaminkhan907 , it's hard to say without any debug information. Have you tried to use the LF-Edge Sandbox before? It's a remote controller that you can use with your EVE device (instead of ADAM): https://lfedge.org/resources/lf-edge-sandbox/
