Hi,

There is a known issue resulting from a recent ConnectWise Patch for 2018.1 that has invalidated internal Passwords used by the Accounting API. We request partners to log a support ticket with ConnectWise Support referring to Ticket #9299516 to know when the issue has been resolved.

For the mean time you can follow the steps for the Work Around:

1. Log into ConnectWise.
2. Click on My Account (top right)
3. Enter your current password, and enter a NEW password. (Note it cannot be the same password used previously).
4. Press Save
5. Log into Wise-Sync, and click on Users
6. Click on your user account (or the one used to sync via the Quick Link)
7. Click no ConnectWise Member Tab
8. Update your new Password, and click 'Test ConnectWise Connectivity'
9. If the password still fails. repeat steps 3 - 4 changing the password slightly.

It is important that you change the password from what you were using previously, as we've found that even after changing the password, setting it back again will result in the same errors.
