Add Self-Signed Certificate Exceptions to Browser

Most browsers require a certificate exception for self-signed certificates. Add a certificate exception for the following URLs.

For production usage, replace the self-signed certificate with a trusted certificate. Follow our step-by-step guide to use your trusted certificate within your domain.

Service	Browser Certificate Exception
`soss-ac-web`	https://localhost:7701
`soss-ac-identity`	https://localhost:9901
`soss-ac-msg`	https://localhost:8801

In Mozilla Firefox, you can add a certificate exception by:

Navigating to Settings (alternatively, type about:preferences into the search bar).
Click Privacy and Security.
Scroll down to the Certificates section and select View Certificates.
Click Servers
Click Add Exception
For location, enter one of the service URLs – i.e. https://localhost:7701.
Click Get Certificate.
Click Confirm Security Exception.
Repeat for all service URLs.

Caution

Generate and install a certificate following our step-by-step guide. The provided self-signed certificate is not intended for production usage.
