31912 - esync-Internet communication failed, 25003 - IP-Read from server failed

Ewon Support Ewon Flexy
#1

Hello,

I had both a flexy and a cosy im trying to put into the same system, I have set both of them up individually (so they arn’t on at the same time). I can connect both to the internet but after about 5 mins the errors below come up:

31912 - esync-Internet communication failed
25003 - IP-Read from server failed

It then wont connect to the internet. If i complete a factory reset, reput all the IP’s it connects then again after 5 mins the same 2 errors come up.

Thanks for response in advance

Hello,

What is the network set up? Is it done by DHCP or Static IP?

It looks like the network could be cutting the connection to the Ewon units after the devices are online for about 5 minutes.

Can you attach a backup with support files of the unit? This can be done with ebuddy while connected to the device.

Hello,

Thanks for your response,

I factory reset both units and uploaded the same config files and it worked,

Thanks

I believe I have similar problem.
I have the EWON COSY131 connected in a static IP network, where all the traffic is allowed, as per the IT words, and although I have internet connection, the EWON cant talk with Talk2m network.

Correct, this is an IT issue. Please refer them to the information here:

https://www.ewon.biz/technical-support/pages/talk2m/talk2m-status/talk2m-vpn-servers

There is more involved than just allowing ports. Make sure they actually read the document.

I sent the document but, just to clarify, here is the backup file I too from the router.

Thanks

Looking at the backup confirms that this appears to be a network issue. Check if they are doing packet inspection on the network. If so, the Ewon will need to bypass this. If the firewall is doing Application Layer filtering, make sure OpenVPN is allowed.

Thanks I sent the info to the customer’s IT.
