Then you can change the NVR password to your own password after you complete the password reset process. You will receive the password from the team.Īfter you have the factory administrator password, you have to log on to your NVR via the monitor which connects to the NVR. ![]() If you have changed the NVR password and get it lost. You have to email to support team to request a factory administrator password. The most secure way to send these mails is to use SMTP authentication – that is, the PHP app uses a username and password to transfer mails to an SMTP server.īut this authentication can sometimes fail with the error: Failed to authenticate on SMTP server with username using XX possible authenticators Almost every PHP application relies on mail functions to send contact requests, newsletters, and more.The default factory NVR password is “password” and its username is “admin”. Here at Bobcares, our Support Engineers maintain thousands of PHP web servers of web hosts, digital marketers, web developers and more. We monitor & maintain these servers, and troubleshoot tech errors. In the course of our work, we see many reasons for the error “ Failed to authenticate on SMTP server with username“. The app was able to connect but the login failed.The PHP app wasn’t able to connect to the SMTP server, or.Simply put, this error says, “ I tried to connect to the SMTP server to authenticate, but couldn’t.” Today, we’ll take a look at the top reasons. Now, why would this happen? Let’s take a look at the top 7 causes. Mail mail servers are armed with brute force attack detectors. It’ll block IPs that seems to be sending automated spam. ![]() ![]() We’ve seen cases where, after a mail campaign or testing, the sending MX’s firewall (eg. Fail2Ban) classifies the web app IP as a spam source, and blocks it. Solution : To fix and prevent this issue, we whitelist the web app’s IP in the firewall, so that it will never be blocked again. Many PHP frameworks such as Laravel use “.env” files to store SMTP connection settings. Sometimes, after an app update or migration, we’ve seen multiple versions of the config file, often with conflicting connection settings. When the app uses the wrong config file, mail connection fails. Similarly, many apps rely on default PHP settings if SMTP settings are not defined within the app. ![]() We’ve seen cases where the SMTP server name or port is specified wrong. Solution : In such cases we systematically go through the app settings and PHP config to eliminate duplicate entries, and fix the PHP config path.Īs a measure to block spam scripts, some web servers do not allow outgoing SMTP connections from web applications. We’ve seen cases where websites that use an external server (eg. Use the local mail server : We help webmasters to reconfigure their app to send mails through the mail server running within the web server.Solution : There are two ways to fix this: Google) to send mails are blocked because of this reason. Whitelist the user : If the webmaster requires an external SMTP server (eg.This fixes the need to establish a remote SMTP connection, and prevents a future block. Connection allowed only via SSL/TLS protocol corporate gateway) to be used, we whitelist the web user to remove limits on mails.Ĥ.
