Rejoin the meeting
Microsoft Teams may be functioning properly, and there can be a glitch only in regard to a specific meeting.

Step 2: Type the name of the person you wish to invite in the search bar or share the invite link.
Alternative step 2: Scroll to the end of the list and find suggested participants, and click on the participant name to add them.
Depending on the meeting settings by the organiser, you will see the option to add directly or share the link. This should help to fix the Teams.Microsoft.com refused to connect error.
