Exchange 2010 - OWA: The connection was interrupted

I am testing a new Exchange server on VM. I set it up and I am able to send/receive emails from/to outside world. OWA works internally without any problems.

When I try to access it from outside, I receive a warning about cert (which means that my web browser is connected to exchange), I agree and reveive:
'The connection was interrupted'

Is it possible, that the server has not enough memory? I run it on 1.5GB. What else should I check

You directed me with this sentence:

could you give us a bit more information on how your exchange is published to the internet?

I tried to access OWA from my PC which is behind the same router. I used RDP and tested OWA and it was fine :)

Hint: never test RDP/OWA from the same network using a public IP, it might cause routing issues

hi there,

could you give us a bit more information on how your exchange is published to the internet?
Is it a simple port forwarding or are you using a reverse-proxy?

It is facing the Internet with a public IP address. MX record points directly to this server. It is behind a router and RRAS though but all port forwarding options are setup
I checked port 443 is opened. I used 'canyouseeme.org'

Is it a single server?

Thx MichaelVH for a quick reply

I have one Exchange server, one DC and one RRAS server in this topology

Quite bizar.

Is there maybe some more information (maybe an error message to work with)?

m1979, as you said it might cause issues, depending on how routing is setup.

I'm glad you got it sorted out!
