Resolução

Option 1: Update your certificates
If you are using Tableau Server with mutual SSL authentication, we recommend updating your certificates to use SHA256 (or stronger) signatures before upgrading to Tableau Server 2020.4 or later.
 

Option 2: Disable has blocklisting as a temporary workaround

As a temporary measure, you can disable signature hash blocklisting with the following command:

tsm configuration set -k "ssl.client_certificate_login.blocklisted_signature_algorithms" -v ""

After certificates are updated to use a secure algorithm, re-enable blocklisting with the following command:

tsm configuration set -k “ssl.client_certificate_login.blocklisted_signature_algorithms” -v “sha1withrsaencryption,sha1withrsa”

NOTE: You can see which of your signature hashes are blocklisted with the following command:

tsm configuration get -k "ssl.client_certificate_login.blocklisted_signature_algorithms"
