1) verify that the date/time of the camera is set and correctly updated.

2) verify the ONVIF port, for most of the IP cameras it’s the same than the http port, but some cameras use a specific port for ONVIF.

E.g. if ONVIF is configured on the 8999 port:

– through http:
onvif://192.168.1.36:8999

– through https:
onvifs://192.168.1.36:8999
