Random disconnections in web-access via UTM9

Hi,

I’m using this product UTM/Astro software at my network entry point (since 2014) to protect my network, and I have an ongoing problems of disconnections in our web-access.

I have this problem for a long time and despite version updates, hardware upgrades and even change of ISP, router and all infrastructure... , the problem still remain the same.

My configuration is a Site-2-Site VPN on IP Sec, with two severs connected to each other. 

The problem happens randomly, many times during the day, and every time it occurs, it takes about 3 mins till the connection is restored.

During this period, all web access is blocked/disconnected, but other non-web connections such as SKYPE and PING are fully connected without any interruptions.

It occurs for about 3 mins or less.. and then it restores to normal state.

 

This happens to any PC in my network on random basis, so its not that all PCs are disconnected on web at the same time, but each of them behave independently.

 

I can restore the connection by disable/enabling the network adapter, but it reoccurs over and over during day randomly.

 

It seems to be related to the web-protection/control parts.

Please advise how I can solve it.

 

Thank you

Alex

    I've checked the logs on both and could not find any problems. 
    I also sent the log files to support@sophos... and they also did not find anything in it.

    Its very strange. And when this "disconenction" occur, I can't even access the web-panel of UTM9 on the remote server, so I can only access the local UTM server and I'm disconnected from the web-backend of the remote-server.
