Re: Lost MDD timeout

Hi cloudmaster9000, 

Thanks for letting us know about your issues with Lost MDD time outs, I apologise for any troubles incurred.

I have tested the connection from here and I can see that there's some time outs inside the Hubs logs, an engineer will need to attend in order to resolve this for you.

I will send you a PM (purple envelope at the top) detailing what's required to proceed with making the booking. Please respond to me there and I'll get this sorted for you.

Take care, 

Thanks, 

Adam.
