Could not connect to Azure cloud hyperscale citus

i tried connecting my local postgresql to azure via hyperscale citus but got this error.

psql: error: could not connect to server: could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "mydemo-c.postgres.database.azure.com" (20.42.29.217) and accepting TCP/IP connections on port 5432?

I tried the steps asked earlier like re-configuring conf files and making available all listening ports but it didn't worked out. Any help?
