TM1 Forum

Hello Everyone,

I would like to have a secure communication between client(Tm1 Restapi) and TM1 Server so I set the

UseSSL = True in tm1s.cfg.

Then I checked the link 'https://localhost:8000/api/vi/Server' in the chrome browser, it works fine. But its not working in IE and firefox. Its saying insecure, why? Do I need to set up anything specific to browser.

My question here is, do we need to buy a seperate SSL certificate for Rest api for Production Environment or by setting UseSSL=true will give us default IBM Certificates which is enough for Production Environment.

Kindly provide me your valuable suggestions and thanks in advance.

You will get warning messages in any browser you are using when accessing an HTTPS link to protect against unauthorized access, something along the lines of:

Chrome/ Edge: NET::ERR_CERT_AUTHORITY_INVALID
Firefox: Error code: MOZILLA_PKIX_ERROR_SELF_SIGNED_CERT

You can bypass these messages by accepting the risks in the browser.

Alternatively you can clear the warning via the following IBM technote: How to Resolve a Browser Certificate Warning - This site is missing a valid, trusted certificate
