Allow outbound connections
Outbound connections from functions are not allowed by default due to security restrictions. Learn how to configure the environment to access external hosts.
Add a host to the allowlist
To perform a call to an external host, you need to allow connections to this host in the settings.
Open the Settings
app from the Dynatrace Launcher on your environment, and select Preferences > Limit Outbound Connections
from the side menu.
Note
After adding or modifying the allowed hosts, the change might take up to 10 seconds.
You can configure allowed hosts by IP address or DNS name. DNS names with at least three segments can start with wildcards.
Examples for allowed entries:
123.123.123.123
www.example.com
api.example.com
*.api.example.com
*.example.com
Examples for invalid entries:
http://123.123.123.123 # Protocol must not be part of the entry
https://example.com # Protocol must not be part of the entry
example.com/api # Only the domain is allowed
*.com # Wildcards are only allowed with at least three segments
123.*.123.123 # Wildcards are not allowed for IP addresses
*api.example.com # Wildcards must match a whole segment
api.*.example.com # Wildcards must be at the beginning of the entry
You can also turn off allowlist enforcement to allow connections to any external host.
