customer paid invoice, but it's not marked as paid in whmcs

[anycolo]

I can see the transaction in transactions, it's marked as 'overpaid', but there is not payment notification received by whmcs. how can i investigate this?

You can check the shkeeper deployment logs with the following command:

kubectl -n shkeeper logs <your_shkeeper-deployment_pod_name>

By default, SHKeeper tries to notify about payment every minute, so unsuccessful attempts should be logged
