Hi,

We have a set of users from a pool which is meant for a different site, they are unable to join the meeting. Once they click on Lync meeting in Lync meeting invite, they get the  error - 

error: A server error occurred. Please contact your support team.

Can you guide me what tests can be performed to troubleshoot this?

Please note: we have 2 sites and the certificate tool checker shows na-join.danahermail.com and eu-join.danahermail.com  certficate to be missing an intermediate certificate. Could that be the cause of the issue or I need to check something else?

Thanks & Regards,

Vinay Mishra

Hi,

Would you please elaborate your Lync Server environment?

Please make sure all FE Server services started as normal.

Please also double check if you configure the correct certificate for FE Servers.

Make sure that you add the meet URL such as meet.contoso.com in internal DNS and in the SAN of the FE Server certificate.

Hi,

The issue cam out to be the EthicalWall. It got enabled after reboot. It was diagonised by analysing snooper in which fabbricadedigitale.it was mentioned which lead my suspicion towards Ethicalwall.

Thanks & Regards,
