Issue/Introduction

We are unable to connect one client to the tunnel server.

 

The error shown in hub.log on the client side is error 0x14090086 certificate verify failed

Environment

Release : 20.3

Component : UIM - HUB

Resolution

This is caused by a firewall policy which does not allow self-signed certificates in the chain.  The UIM Tunnel server by default uses a self-signed certificate to authenticate the clients, and the firewall must allow this.
