Teamwork / BimCloud Basic slow send/receive

[pr3]

Hello everyone.

Since switching to AC28 we experience very slow send/receive times. (1-4minutes - before it was just a few sec.) 

We do not have any issues with our network whatsoever.

We bought a new macMini running the Teamwork Server and nothing else.

The Newest version of BimCloud Basic is running.

Graphisoft support does help very little.

I would appreciate some ideas / input.

Thanks
