Domains, Protocols and Ports required for Loom to work on your servers

If you're recording on a protected network, there can be firewalls/proxies blocking Loom. This can block your ability to record successfully.

Issue symptoms

Repeated failed recordings (video ending prematurely, can't start a recording, etc...).
Loom application displays as a blank box.
Abrupt recording endings - due to 1006 websocket error.
Recording error from Chrome.

Here's how to fix this:

Allow the below Domains and Ports in your firewall.

When whitelisting access for Loom, it's best to whitelist all addresses listed under "Domains" in order to ensure future services we add behind a new subdomain don't get blocked. In the case you're decrypting SSL traffic and are having issues, please turn off decryption to non-URL SSL traffic on your network.

Please whitelist:

*.loom.com
icanhazip.com
api.ipify.org
cdn.segment.com
api.segment.io
*.intercom.io
*.s3.us-west-2.amazonaws.com
*.logs.datadoghq.com

These are the whitelist specifications:

Domains

www.loom.com
record.loom.com
cdn.loom.com
luna.loom.com
proxy.loom.com
location.loom.com
packages.loom.com

Protocols

wss
https

Ports

80
443

To do this, you may need to contact your network administrator to configure your firewall and allow the above. We recommend exempting all the addresses from any type of scanning (ex: SSL decryption, Anti-virus scanning).

If you want to use IP address ranges rather than DNS domains, e.g *.amazon.com , then Amazon have published a handy web page that enables you to find the IP address ranges used with AWS here.
