If you are having issues logging into avamar and you see the following message “com.avamar.asn.NetworkException: Unable to connect to a login server” then the issue is usually environmental. Avamar 5.x relies heavily on DNS and improperly configured DNS will cause this issue.

If you are using windows AD for DNS, then make sure that DNS records are setup in the same domain as the domain that Avamar was setup in. If they are and still having this issue, remove duplicate avamar records from subdomains. This should resolve your issue.

If the DNS server is unix/linux based case sensitivity is usually the culperate.
