SD RED 60 Can not do SSL handshake on Socket accept from

Hi,

We have a deployment from around 21 SD-RED 60 which are working fine.

Now I need to test something and want to deploy another SD-RED 60 which was also working fine in the past. But now the RED cannot open a Tunnel and the red.log shows the following.

I tested another RED which has the same issue.

Regard´s

Silvio

Hello Silvio F ,

Thank you for reaching out to the community, SD-RED 20 & SD-RED 60 uses TCP 3400 + UDP 3410. And under the logs we can see the SSL handshake is failing.
Under the advance shell, you may check via: #telnet red.astaro.com 3400

Thanks & Regards,

Hello Vivek,

I know, thats what this log is showing. I want to know why the ssl handshake is failing because it makes no sense to me. This RED was in use till a week ago without any problems. I have the same Issue with another RED which was also in a productive Environment but now has issues with the SSL Handshake.

I can connecto on 3400 to red.astaro.com

Regards

Silvio

What are you looking for exactly? As I mentioned above, there are 21 Reds in place, and if I dump for any Port 3400, there will be a lot of noise.

But now I´m perplexed. I changed the Gateway to an other IP for the Red and the tunnel is established. But this doesn't make any sense.
