When configuring the Microsoft Teams integration, on step 8 the xMatters hostname is entered but no connection is established.
An error appears when the host name is entered as https://company.xmatters.com.
All versions of xMatters On-Demand, Microsoft Teams bot integration
Your xMatters environment may have been set up with a different hostname, such as https://company.hosted.xmatters.com or https://company.na1.xmatters.com. Make sure you're using the hostname for your xMatters instance.
For SAML-enabled environments:
When using Single Sign-On with xMatters, log into xMatters using SSO before you start configuring the integration. This bypasses the xMatters login screen and takes you directly to the Allow Access screen. Note: you still have to click Sign in to complete the connection in the background.
DNS may not resolve the "friendly" hostname during the connection process. The original/alternate hostname should bypass this problem.
