IE return error while attempting to access Gplus Adapter for MsCRM

[cpoon]

Hi

I've configured a multi-site environment with Gplus for MsCRM installed.

On local site (where all servers reside), the local agents are able to access the Gplus adapter on IE.

However, remote agents on remote site are not able to access, IE will return the following error:

Client must enable encoding 'gzip' in order to retrieve this resource.

Has anyone encountered similar error before? Please advise.

Thanks in advance,
