Re: Cannot login to Trio 8800 using Skype for Business Credentials-Failed to fetch the root certific



Welcome to the Poly Community. I have moved your post here.

The Log shows:


0907131139|ldap |4|00|ldapData::ldapConnBind:ldap_x_bind_s - rc=0xffffffff <Can't contact LDAP server>
0907131139|sip  |4|00|[cert_verify_callback,tcp]:Server certificate verification failed, Untrusted Certificate,error=20

We would need to see more logging.


I can see this Trio was sold via First Video Communications FZ-LLC back in 30/03/2019 so its still within warranty.


I suggest, rather than playing log ping pong via the community you contact your reseller so they can support you.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier
