Avalara Tax Connect Certificate Change May 2017

Has anyone else had issues applying the Avalara AvaTax SHA1 Certificate Change May 2017? I thought I had imported them with keytool but I am still getting the error.

Ping Tax Service - Error Found: ; nested exception is; javax.net.ssl.SSLProtocolException: java.io.IOException: subjet key, Unknown key spec:Invalid RSA modulus size.

We had issues. Had to change the TaxConnect URL

The old one had sha-1 in tge url.

Edit: old one was avatax-sha1.avalara.net

Thank you that was it! Always seems to be 1 small step missing.
