Question

My FQDN addresses sometimes cannot resolve names over firewall.

Hello there,

My FQDN addresses sometimes cannot resolve names over firewall.

In general, I organize the problem as follows;

1-) I restart the DNS server.
2-) I delete the FQDN address and add it again.

How can I solve this problem? Can I solve it by running a command in any CLI?

Thanks.

Please try run the command :

di test application dnsproxy 7

By running the command, you could check the ip address for the particular domain name.

Please try to send the dns query from end user and make sure that the DNS ip address is configured on the client to verify if it getting resolved from the client 

You could also increase the dns cache ttl value :

config system dns
set dns-cache-ttl 1800
end
