Can not connect Fedex Acct - Invalid Billing Address

Hello there Pablo396! 

Thanks for taking the time to join the community! We are thrilled to have you with us.

When getting this type of error message, it is best to first double check the billing address as it is listed directly from the FedEx website when logged into this account. 

If this has already been what's attempted, it would be my recommendation to reach out to the Support Team directly so they can troubleshoot that specific account connection with you in more detail. 

I hope this helps! 

I am having the same issue... Can someone tell me how this was resolved?   
I have checked the billing address.  It is correct.  
Not sure how to fix this.

Thanks

Also having this issue.  Why has this still not been addressed for a major carrier like FedEx?

For anyone reading this since it has never been addressed after all this time.  There are two connections for Fedex.  One is UK, one is US.   Neither are labeled (unless you hover)
