Error 18
Starting with the Salesforce Summer ‘23 release, the OAuth 2.0 username-password flow is disabled by default. If this functionality is not enabled, Service Board tenants fail to connect to the associated Salesforce orgs and the following error appears:
ERROR [c.i.i.sfdc.SFDCHelper] [ ] [ EMP Connector heartbeat timer] Failed to get SFDC token, status is:400, response is: {\"error\":\"invalid_grant\",\"error_description\":\"authentication failure\"} "
On the Salesforce Login History page, the related error message is Username-Password Flow Disabled.
To address this error:
• On the Salesforce Setup page, in the left pane, click Settings > Identity > OAuth and OpenID Connect Settings, and then on the OAuth and OpenID Connect Settings page, enable the Allow OAuth Username-Password Flows option.
