You most likely forgot to tell your UF where your central Splunk instance is located. On a Windows UF, you could do this during installation (it's asking for a Deployment Server IP).
After installation, go to Splunk UF install directory, go to subdirectory bin, run splunk.exe set deploy-poll IP:8089, where IP is the IP/hostname of your central Splunk instance.

Alternatively, and cleaner for later management, would be to go to Splunk UF install directory, go to subdirectory etc/apps, create a new directory deploymentclient-config, create a subdirectory default, create a file named deploymentclient.conf, put this in the file:

[deployment-client]

[target-broker:deploymentServer]
targetUri = deploymentserver.splunk.mycompany.com:8089

Again, replace it with your IP/hostname.

If that doesn't work, check for a firewall issue between UF and central Splunk.

Okay, your connections time out. In 99% of all cases, this is a firewall related problem, because firewalls tend to silently drop requests that are not allowed, creating timeouts when trying to connect.
You should check with your network security people, they're most likely able to help you.

I opened 8089 port from firewall
for both inbound and outbound calls

I am configuring a splunk cloud with a universal forwarder in my local machine.
I think i am providing wrong deployment server.

I provided domain of splunk cloud url as deployment server. is that correct?

Ah, I missed the part about Splunk Cloud.

The docs say this:

To enable you to use Splunk Web to
manage forwarders and configure data
inputs) In the Deployment Server
dialog, enter your Splunk Cloud
hostname in the Hostname or IP field.
Specify the URL provided in your
Welcome email, omitting the leading
https:// and preceding the URL with
"input-". For example:
input-prd-p-z41nh2qlt7cx.cloud.splunk.com.
(Note: When you install the universal
forwarder on other platforms, you must
configure the deployment server/client
settings manually by editing .conf
files. On Windows, this logic is
included in the installer.)

Check this: https://docs.splunk.com/Documentation/SplunkCloud/7.0.0/User/ForwardDataToSplunkCloudFromWindows
