Sometimes you may see the following message on the CFA:

"Operations have been suspended due to: Failed to contact Infrascale for more than 72 hours."

Most common reason for this to happen is something blocks the CFA from reaching our billing or license server. To check if that is so please try following:

1. SSH into the CFA.

2. Run following commands:

nc -vz 443

nc - vz 443

a. If some of those are not resulting in the proper connection, that means that something blocks port 443 for the CFA.

b. If both of them commands are resulting in the proper connection proceed to step 3.

3. Run following commands:



a. If some of those commands are giving you the reply, that means that there is some issues with DNS which points at the wrong server. The name of the wrong server is in that ping reply. For example:

PING ( 56(84) bytes of data.
64 bytes from ( icmp_seq=1 ttl=59 time=36.5 ms
64 bytes from ( icmp_seq=2 ttl=59 time=31.9 ms
64 bytes from ( icmp_seq=3 ttl=59 time=29.7 ms

In this particular example the wrong server is "".

Also you can try running following command that would help to identify the root cause:

cat /dev/null | openssl s_client -connect

cat /dev/null | openssl s_client -connect

In case if CFA would get proper reply, he output will contain the folling string:


b. In case if the ping does not give you reply, [contact]({:target='\_blank'} Infrascale Support.
