Nextcloud Onlyoffice out of space

hello mundo,

I try to put onlyoffice on my nextcloud but I have this message and i don’t understand anyhting:

Erreur durant la tentative de connexion (cURL error 60: SSL: no alternative certificate subject name matches target host name ‘10.0.0.0’ (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for https://10.0.0.0/nextcloud/index.php/settings/admin/onlyoffice/healthcheck)

if a nice person could give his light to see in this dark world of installation of oNLYOFFICE on my nextcloud server, it would be very nice ! thank you !
