Unable to configure syslog with tcp protocol via WebUI

[r-nd03]

Tried for the first time to configure the EventForwarder via the CB Response WebUI.
I was previously configuring the Event Forwarder via the config file and using the "tcpout=<fqdn/ip>:port" configuration.
The WebUI doesn't provide the option for a TCP output under "Type" and the new destination format (://[:]) has failed for me when I tried the following:
Type: syslog
tcp://syslog.localdomain:5514
tcp://10.10.10.10:5514

Error message: level=fatal msg="Error connecting to 'tcp://10.10.10.10:5514': dial tcp: lookup //10.10.10.10: no such host"

From my Event Forwarder / CB Response server I'm able to ping my syslog server without any issues via the IP or FQDN, I've even disabled my syslog server firewall just to make sure.

The only method I found for the process to start was by omitting the "" and using only this "://syslog.localdomain:5514". However, I believe it's a bug as the process starts but nothing is forwarded (no network comms observed via tcpdump) nor does it write anything to an outfile.
