Not able to connect to repository

[shivam-sood98]

Hi, we are trying to migrate rtc code stream to git. But unfortunately, we are seeing repository connection error. Credentials and URI provided is correct and tested, but with scm login it is not working thus blocking us from migration.

C:\Users\Administrator>scm login -r https://host:port/jazz -u [email protected]
Password ([email protected] @ https://host:port/jazz):
Problem running 'login':
Could not log in to https://host:port/jazz as user [email protected]: CRJAZ2384E Cannot connect to the repository at URL "https://host:port/jazz", see the nested exception for more details.
CRJAZ2384E Cannot connect to the repository at URL "https://host:port/jazz", see the nested exception for more details.
Check the log for details about the error at "C:\Users\Administrator\AppData\Local\jazz-scm". If you have configured custom logging check your log configuration settings for the path to the log file.

Could anyone please help here?
Thanks in advance.
