If you are trying to connect to a webinar from a work, school, government, or religious organization, you may run into a Firewall issue. Below are a few steps you can take to identify if you are behind a Firewall and what to do next.
When joining an event or webinar on BigMarker, if a network Firewall is enabled, you may see a black video screen or a "Connection Can't Be Established" warning. A firewall may also cause a dropped connection (around every 10 seconds). Similarly, those behind a firewall might not be seen or heard by other presenters in the room.
Note: If webcast mode is enabled, attendees should not be impacted.
Actions you can take:
If possible, contact your IT department and have them open the necessary Ports (see below).
Minimum Requirement: Assumed by default is that TCP ports 80 and 443 are open. Some firewall rules only allow for TCP traffic over port 443, make sure that all traffic can pass over this port. If you continue to experience issues, you may need to follow the rest of the rules below.
Best Experience: In addition to the minimum requirements being met, we recommend that UDP ports 1025 - 65535 be open.
More info: Our streaming server IP addresses change dynamically and can be any IP address, so you cannot allowlist an IP address range. If you are looking to add our domain to be allowed in your firewall, the easiest thing to do is to allow traffic from all bigmarker.com servers with *.bigmarker.com domain.
Explicit Firewall rules for your IT department:
443/tcp ALLOW *.bigmarker.com
80/tcp ALLOW *.bigmarker.com
80/udp ALLOW *.bigmarker.com
53/udp ALLOW *.bigmarker.com
443/tcp (v6) ALLOW *.bigmarker.com (v6)
80/tcp (v6) ALLOW *.bigmarker.com (v6)
53/udp (v6) ALLOW *.bigmarker.com (v6)
53/udp ALLOW OUT *.bigmarker.com
80/tcp ALLOW OUT *.bigmarker.com
443/tcp ALLOW OUT *.bigmarker.com
443/udp ALLOW OUT *.bigmarker.com
53/udp (v6) ALLOW OUT *.bigmarker.com (v6)
80/tcp (v6) ALLOW OUT *.bigmarker.com (v6)
443/tcp (v6) ALLOW OUT *.bigmarker.com(v6)
443/udp (v6) ALLOW OUT *.bigmarker.com (v6)
If this does not work, have your IT department email support@bigmarker.com
Troubleshooting Tips:
-
- If you are behind an Application Firewall BigMarker will not be able to penetrate it unless it's disabled. So if possible, disable the firewall or VPN.
- Try switching to a personal device and/or network.
- Try connecting to a hot spot.
- Instead of using your computer's mic, use the dial-in option within the mic settings. (long distance charges will apply outside of the US/Canada region)
- Disable anti-virus programs (ex: Kaspersky, Norton, McAfee, AVG, Windows Security Essentials, etc. Be sure to also disable Windows Firewall). Programs like these consume CPU resources, and may block ports needed for a successful webinar experience.
- Disable privacy/security browser extensions.
