In Sage 100, why am I receiving the following error: "Internet Connection is down or the URL specified in AvaTax Connect Options is invalid"?

Overview

You are trying to validate your credentials in Sage 100 and receive the following error:
"Internet Connection is down or the URL specified in AvaTax Connect Options is invalid. Proceed as normal. Check AvaTax Connect User Manual for instructions."

Environment

Sage 100

Resolution

  • As the error suggests, check the Internet connection.
    • See if you can ping our service URLs
    • Your network settings may need to be updated
      • Make sure you have proper permissions on your network
      • Make sure you do not whitelist Avalara's IP addresses or the range of IP addresses Avalara uses
        • Whitelist the domain avalara.net and @avalara.com
  • This error also happens if the credentials are not correct.
    • Make sure the Username, Password, License Key, Account Number, URL and Company Code are for the same account
    • You may test your credentials here
  • Finally, this error can indicate that the avatax.avalara.adapter.dll is registered in two different locations on the same machine. 
    • If this is the case, unregister both, delete the duplicate dll and register the dll in the proper location (usually the MAS90 folder).
    • DLL registration directions are found here
