Because our plugins and addons rely on a connection to our website's API to verify account purchases, users may encounter a "no internet" error message when the plugin or addon cannot make an outgoing connection.
Common Fixes
The two most common blockers for our plugins are:
User Firewall settings
Antivirus software
It's recommended to temporarily disable these and test the plugin connection again if you're experiencing a connection error.
Tried the above, and still not able to connect? Proceed with the next steps:
Connectivity Test
On your operating system command line prompt, verify this returns ok:
> curl https://apiv2.poliigon.com/
Should respond with:
{"message":"welcome to poliigon-api-production-eu"}
Inside your software's python console: Try this first, one line at a time
import requests
url = "https://apiv2.poliigon.com/"
res = requests.get(url, timeout=20)
print(res, res.reason)
A "good" (or rather, expected) response would be:
<Response [200]> OK
If this fails to connect, then try the following, to verify you can access non-poliigon internet (one line at a time):
import requests
url = "https://www.google.com"
res = requests.get(url, timeout=20)
print(res, res.reason)
a "good" response would be:
<Response [200]> OK
If you're getting responses that are different from the expected responses listed above, you may have a general connection issue, which may require individual investigation.
If you've got the expected responses and are still not able to connect, and/or you're working in an office managed by an IT department, you may need to whitelist domains in order to connect, in which case proceed with the following.
If you are using Blender, consider starting it from the command line in a debug mode and retrying the tests above: .\blender --debug
This may reveal further connection details.
IT Department Domain & IP Whitelisting
Domains
If you can whitelist at the domain level, the following list is the current domains in use as of 27th Aug 2025.
Please note we do change our infrastructure from time to time, if possible whitelist all poliigon.com subdomains in addition to the non-poliigon.com domains listed below.
IP Ranges
If you are unable to whitelist domains and need to whitelist IP ranges, below is the current list as of 27th Aug 2025.
Please note this list changes regularly so we do not recommend this approach.
Note: algolia.net does not provide IP blocks
