SFB SRS we can't sign you in because the server couldn't be reached or the server version is incompa

Hi,

We have a demo for the logitec smartdock.

We have a hybrid env with ADFS.

This is what we did.

Create  user onprem. (pw never expires)

synced to the cloud

create mailbox onprem

migrated mailbox to cloud

changed mailbox to room  Set-Mailbox mail@domain.com -Type Room

Then we added the proper license E1

Then i logged in to sfbonline  powershell and did the following command.

First found out what our registrarpool was.

Enable-CsMeetingRoom -Identity mail@domain.com -RegistrarPool 'ourdomain.com' -SipAddressType MailAddress

When this was ok i tryed to logon to sfb on my phone with new user this is no problem.

However when we add the credendtials to the logitech smartdock we get following error.

we can't sign you in because the server couldn't be reached or the server version is incompatible.

Device is not joined to the domain.

Any ideas ? 

Kind Regards,

David
