and a proxy server with local database

All mariadb databases

Added proxy server under Proxies and it is last seen OK
if the host is set under "monitored by proxy" with the Proxy Server, the host's availability is GREY

----------------------------------
Connected to IP
Escape character is '^]'.
Connection closed by foreign host.

Please help. The host when monitored by Proxy is not working. The availability is GREY even though there are items and templates attached.
