Cannot connect to cas using sas studio v

[woo]

Hello, 

we have viya 3.5 installed on rhel. when try to run below code, receive tcp/ip error

options cashost="hostname.com" casport=5570;

cas;

Error: The TCP/IP tcpSockConnecy support routine failed with error 111 (the connection was refused)

Error: failed to connect to host 'hostname.com", port 5570

Check your CAS host firewall rules to ensure communication on port 5570 is allowed. Also suggest raising a Tech Support track as firewall rules is only one of many possible causes that may require diagnosing.

Hello @woo 
What client are you using to connect?

[woo]

Thank you but this got resolved. some patches got applied Unix side and somehow ownership of few files has been changed (don't know who). Putting ownership back in place seems resolved the issue.
