Have you or one of your Users changed a password and tried connecting AssetAccountant back to Sage Intacct but failed?
You may have received a "invalid credentials" notification.
It may be a simple case of remembering to ensure your individual Username/email address you use for Sage Intacct still matches what you setup in AssetAccountant.
It is important these match identically - so please check this.
Sometimes, this error is also triggered by the User in question being locked out in Sage Intacct.
Only your Sage Intacct supplier can fix this error for you.
You may also try disconnecting and reconnecting the integration, but this only fixes simple most-recent software update incompatibilities and may not fix a broader account integration connection.
Unfortunately, AssetAccountant has no direct access to individual Sage Intacct platform accounts so we cannot advise which username was used to connect AssetAccountant to Sage Intacct in the past.
In any case, the "invalid credentials" error is usually not related to an individual Sage Intacct user's personal account.
It is typically a special, Web Services account which has the permissions necessary to enable broader access to Sage Intacct.
Here is a link to our configuration guide, which explains this further and should be actioned at your Sage Intacct administrator access level: Sage Intacct configuration guide.
