VMware UAG – not resolve Horizon Destination Server
i just upgraded the customer VMware UAG – VMware Unified Access Gateway from version 3.9 to the latest 22.03, but after import .json file from the old one appliance i had problem with „Horizon Destination Server“ in the Horizon Settings. I check the thumbprint of certificate on the destination server certificate but no issue found.
So i connected to the UAG appliance via SSH client and check the DNS settings, i found that my appliance not resolve the domain „horizon.xxxx.xxx“ and this is issue.
It appears that the new systemd-resolved method uses .local for multicast DNS exclusively. Way to fix this issue is edit /etc/systemd/resolved.conf and uncomment the domains line and adding in your .local domain to the domains there.
