"Invalid login attempt" Error Message

If you see an error message saying invalid login attempt it could be that Shiptheory's integration record has been marked as blocked. While blocked you cannot connect NetSuite to Shiptheory. To check if the integration record is blocked go to Setup > Integration > Manage Integrations


Once on the integrations page check to see if you can find the integration named "Shiptheory". If, for whatever reason, you have multiple integrations called Shiptheory, then the integration record's ID to check for is "custinteg_e742b0f7af61". 


If you can see it and it is marked as "Enabled" then no further action is required. If you cannot see it, check the box called Show InactivesThis will display all integrations, blocked and enabled.


If "Shiptheory" is marked as blocked then edit the integration and change its state from "Blocked" to "Enabled" and save your changes.
