Hello @marques neto,

Thank you for reaching out here. We want to welcome you to the Docusign Community. I appreciate you bringing your question to this Community, and we are committed to providing you with the best service possible.

I apologize for any inconvenience this might cause you. Is this error showing in the Docusign end? If yes, are they trying to sign the envelope on a computer or a mobile device? Have you tried the below troubleshooting:

• Clear cache/cookies
• Try a different browser(s)
• Try an Incognito window
• Try a different device
• Try a different Internet network, such as on a mobile device using data with Wi-Fi disabled.
• Try using a VPN, or if you are on one already, disconnect from the VPN and try again.
• Please try the Alternative Signing Method

Note: Some advanced features and options are supported only in specific Docusign plans. Your account plan might not support some of the options discussed in this help topic. Contact your account administrator for more information about which options are available for your account. Or, visit our Plans and Pricing web page for more details on the features included with your plan. Compare eSignature plans & pricing.
