Cumulus Support

hi guys, finally everything works!
Probably the problem was in the altervista site, since by default the server-to-server connections are limited to a whitelist that contains only a few addresses.
By elimiting the whitelist, and then leaving the server-to-server connection to all addresses without restrictions, everything works.
The thing that I found however, is that the site seems slower to load ....

Excuse me guys, how come sometimes the station goes offline even if it continues to broadcast? that is, the graphic temperature data etc. are updated but on the altervista site it is given offline.
The raspberry is turned on and cumulus runs normally.
