Stream only connects using IP Address

issue client is having dns issues can connect by ip but not full io url provided by zen master when a system connects to a service using a hostname (for example zaas la kekbz cstest io zixi com), it must first perform a dns lookup dns (domain name system) translates the human readable hostname into a numerical ip address that computers actually use to communicate the process is the client asks a dns resolver to resolve the hostname the resolver returns an ip address (or multiple ips) the client then connects to that ip address if dns resolution fails, the connection attempt never reaches the service, because the client does not know which ip address to use why connecting by ip can still work when you connect directly to an ip address, dns is completely bypassed that means · no hostname resolution is required · no dns servers are queried · no dns cache or ttl behaviour is involved as long as · the service is running on that ip, and · the network path to that ip is reachable the connection will succeed, even if dns is broken we have not made any dns changes but it could have been a cache in a dns that was stale on the encoder network you could test the following nslookup \[insert zen master io url here] 8 8 8 8 nslookup \[insert zen master io url here] 1 1 1 1 i expect to see · the hostname resolves · one or more ip addresses are returned · no errors that confirms dns is working for that resolver if dns is not working it will look something like this server can't find hostname nxdomain resolution investigate your dns configuration for the host host machine configure dns settings permanently using the appropriate configuration method for your respective os, such as editing netplan yaml files or using the networkmanager check your network & dns settings within the zixi broadcaster as the team the network configuration tab within the broadcaster ui has been deprecated as of version 17 and should not be used with newer os that use networkmanager or netplan (as in the case of ubuntu)
