I made a single change to my destination_port_range:

      ~ security_rule       = [
          + {
              + access                                     = "Allow"
              + description                                = ""
              + destination_address_prefix                 = "*"
              + destination_address_prefixes               = []
              + destination_application_security_group_ids = []
              + destination_port_range                     = "21"
              + destination_port_ranges                    = []
              + direction                                  = "Inbound"
              + name                                       = "SSH"
              + priority                                   = 1001
              + protocol                                   = "Tcp"
              + source_address_prefix                      = "*"
              + source_address_prefixes                    = []
              + source_application_security_group_ids      = []
              + source_port_range                          = "*"
              + source_port_ranges                         = []
            },
          - {
              - access                                     = "Allow"
              - description                                = ""
              - destination_address_prefix                 = "*"
              - destination_address_prefixes               = []
              - destination_application_security_group_ids = []
              - destination_port_range                     = "22"
              - destination_port_ranges                    = []
              - direction                                  = "Inbound"
              - name                                       = "SSH"
              - priority                                   = 1001
              - protocol                                   = "Tcp"
              - source_address_prefix                      = "*"
              - source_address_prefixes                    = []
              - source_application_security_group_ids      = []
              - source_port_range                          = "*"
              - source_port_ranges                         = []
            },

But now I’m unable to access my VM:

port 21: Connection refused

Revert such single change I can connect again.

What would be the fix to open port other than 22 please?

It sounds like you are changing your “firewall”, but forgetting to change the port your SSH server actually listens on.
