RED 10 (rev1) not connecting anymore

Hello,

I have a problem with an old RED 10 (revision 1).  This RED 10 connects to an ASG 120. This connection worked fine for years.

The problems started once the customer replaced two old cisco routers on the route between the RED 10 and the ASG 120. When the new routers are in place the connection fails, when the old routers are in place it works.

When the red 10 is powered on, I can see on the ASG 120 that it tries to connect:

After this initial try, the log just goes on like this:

On the panel we have power, system and interet on, and the tunel light is off. No blinking.

Anybody got an idea, what the problem might bee?
