I’ve run into something very similar before. Usually, this error (“Error! There was an error loading your AWeber lists. Please try again.”) points to one of these issues:
* Your OAuth/token authorization was invalid or expired — re-authorize the integration
* The server time on your host is off (AWeber’s API checks timestamps) ([help.aweber.com][1])
* Permissions/scopes (access rights) for the integration are insufficient ([help.aweber.com][1])
* AWeber’s API could be rate-limiting your connection due to too many rapid requests ([help.aweber.com][1])
To debug, I’d suggest:
1. Disconnect and then re-connect the AWeber integration (generate new credentials).
2. Check your server’s clock and sync it to an NTP or reliable time server.
3. Make sure the integration is asking for all the required scopes (permissions).
4. Test from another site/environment to isolate whether it’s your host or plugin.
If you like, I can dig into your specific plugin setup. Meanwhile, you can check more details on this **[site](https://deepseeksguides.com/)** if it helps you see examples of properly configured integrations.
