Check_MK (MULTY SITES - ssl.c: 711: Handshake operation timed out)

[Gustavo]

Hi,

I have a question about the encryption of the slaves, I already configured some slaves and encrypted without problems, but the next day the connection status (ONLINE) changes to:

** Cannot connect to ‘tcp: x.x.x.x: 6557’: (’_ssl.c: 711: Handshake operation timed out’,). The encryption settings are probably wrong. **

And in other slaves I can’t do the configuration, because I get this error:

** Cannot connect to ‘tcp: x.x.x.x: 6557’: [Errno 114] Operation already in progress **

I have other slaves with the same configuration working fine, I try to use persistent connections and it is not working, TLS is enabled in omd configuration for my slaves and also restarting OMD on slave but state does not change.

Can someone tell me what to do?

My CMK Version is 1.6.0p15

Livestatus error: ('_ssl.c:711: The handshake operation timed out',). The encryption settings are probably wrong."

Hello, I have deployed a CMK cluster, version 1.6.0p7-raw. There is one master and 3 slaves and they have configured SSL Encryption. The deployment works fine but in a random way you can see errors like “Cannot connect to ‘tcp::6557’: (’_ssl.c:711: The handshake operation timed out’,). The encryption settings are probably wrong.” Does anyone know why this happens? You reload webpage and everything works fine but this error appears randomly. Thank you in advance. BR, Jose

Perhaps a hint?
You can find one or two more article searching for ssl.c 711
