Need to check whether HTTPS port 443 is Open for Outbound Communication.

Hi Karthik,

Where do you want to check this?

Can you explain more on this?

Hello komuru

If you want to check if a port is open for outbound connection then it means the port should be open for inbound traffic from the 3rd party.

From a servicenow perspective we do not have any kind of port restriction for outgoing traffic. Just ensure the port is open on the 3rd party and it is allowing servicenow IPs to communicate to it.

Hi Karthik,

You can use netstat command to list the tcp port, if 443 port is listed there and state is established means 443 is open for outbound communication.

Please see the below screenshot to check the output of netstat command.

Thanks

Rahul

Sure, you can check if HTTPS port 443 is open for outbound communication in ServiceNow by using the 'Test Connectivity' feature. Here are the steps: 1. Navigate to System Diagnostics > Stats > Stats. 2. Scroll down to the 'Test Connectivity' section. 3. In the 'Host' field, enter the IP address or domain name of the server you want to connect to. 4. In the 'Port' field, enter 443. 5. Click 'Test'. 6. If the port is open, you will see a message saying 'Success'. If the port is closed, you will see a message saying 'Failure'. Please note that this test only checks if ServiceNow can establish a TCP/IP connection to the specified IP address or domain name on the specified port. It does not check if a specific service (like HTTPS) is running on that port. nowKB.com
