Hi,

I have been getting the following CAS errors, continuously for a very long time. My logs in Environment Manager were not displaying any data. I corrected the issue, so now I am seeing a lot errors (probably from day one).

MAIN NoUser MAIN [httpscomm.c:598] - Encryption run-time execution error

MAIN NoUser MAIN [httpscomm.c:597] - Error reading HTTP header from client.

 

The configuration of port 5570 seems to be OK.

Anyone have any suggestions on what I can try?

 

Thanks.

Note that HTTP connections should go to port 8777 not 5570. This message is probably from a client trying to establish an insecure connection (i.e. no TLS) to the HTTP port, so the connection is failing. It's not a problem on the CAS side.

So what do you suggest that I do to correct the issue? Find where the calls are being made from the client and change ‘http’ to ‘https’ or vise-versa?

Yes, to prevent the message you would need to track down the connection attempt. The CAS log (/opt/sas/viya/config/var/log/cas/default/cas_date_hostname_pid.log) might have some additional information on where this request is coming from.
