Thank you for your response. I tried to directly use one of the ip adresses associated with smtp.gmail.com but the result is the same (identical error). I didn't try the ip address you are suggesting because it does not appear to be a google ip address. What exactly is that address ? Why do you thing it should work ?

Hi all, I've been using several hikvision network cameras (2512 and 2412 both with 5.3.0 firmware) for a couple of months without any problem. Suddenly, on the last tuesday, email alerting has stopped working simultaneusly on all the cameras. I tried the test button in the email configuration panel and it says "cannot contact test server". I'm using a google account with this settings: smtp.gmail.com port 465 ssl enabled username: myaccount@gmail.com password: (a specific app password, because i have 2 step authentication enabled) This configuration has worked for a couple of months without any problem. After the problem came up I rebooted all the cameras and i did those tests: 1) I verified internet connectivity from the camera and it was ok 2) I verified that the camera can resolve hostnames 3) I created a different app password and tried to use it (same error) 4) I tried to use different port (465/587 with or without ssl) Nothing seems to solve. I'm absolutely sure email sending was working fine till 17th may 2016. Anyone else is experiencing something similar ? Any help is very appreciated, i honestly don't know what else i could try. Thanks in advance
