Hi  @treesa_123 ,

Please follow this article to make sure both certificates and other settings are correct. 

You can try the following:

1. Clear the Secure Sockets Layer (SSL) state. To do this, follow these steps:

  • In Internet Explorer, click Tools, and then click Internet Options.
  • Click the Content tab, and then click Clear SSL state.

2. File -> Options and Setings -> -> Options -> Security -> Cetificate revocation



Best Regards,

Liu Yang

Hi @treesa_123 


To me the error indicates that there is an issue with the encryption and the SSL certificate where you are trying to connect to?
