Test the connection

You can test your changes within Retool to make sure your deployment can reach the new IP addresses:

1. Sign in to Retool and navigate to the Query Library.
2. Click + New to create a new query.
3. Select the REST resource and GET action type.
4. Set the URL to https://reachability-test.retool.com.
5. Click Save to save the query, then click ▶ to run the query.
6. If the query returns a 200 status and OK status text, your deployment can successfully reach the new IP addresses.

HTTP proxy connections

Retool supports connections to the internet through a HTTP proxy. Add HTTP_PROXY=http://example.com:8080 to your deployment's docker.env file with the required URL and port number.

License checks

Retool uses HTTP to connect to licensing.tryretool.com on port 443 to verify your license. License checks are made at least once a day.

Inviting users

Retool connects to invites.tryretool.com and email-service.retool.com on port 443 when inviting users. Retool verifies the users are authorized under your current billing plan, and then sends an invite to their email address.

Usage reporting

Retool sends application usage information to p.tryretool.com on port 443, which is used to inform product decisions. Some examples include:

• Page views, along with the page URL.
• Query saves, including the query name and type.
• Component creation and the component type.
• Query preview, including the query name and type.
• Adding a resource, including the resource name and type.

Events are also sent with the hostname and the user's email address.
