@NehaMatle-0217 Apologies for the delay in response and all the inconvenience caused because of the issue.
As mentioned here Whenever anyone that does not have a can-use permission tried to log in to Confluence, they will be presented with that page.
The fix is to add that user to have a can-use permission, or add that user into a group that has a can-use permission in the Global Permission page, only accessible by Confluence admin.
Please find more information about this issue, and how to amend it from this documentation.
Also note that Confluence is currently not supported in the Q&A forums, the supported products are listed over here https://docs.microsoft.com/en-us/answers/products (more to be added later on).
If you have any further queries, I suggest you can ask the experts in the dedicated forum over here:
Hope it helps!!!
