VMware View Desktop Error 'The Display Protocol for this Desktop is currently blocked by a firewall'

This issue may Cause because of one reason Windows Firewall is restore default or some changes in firewall by any application.

Normally VDI desktop Should have Below mentioned program allowed and also firewall port should be open

Here you can see there is No VMware Program and firewall port details. since user has change firewall to default there is no view related program or port is allowed.

Now, we will manually add required apps and port.

Go to windows firewall and open Allow Programs or feature through firewall.

Click Allow another Program

Click on Browse..

Go to path C:/Program Files/ Window Media Player and click Open

once this is selected Click on Add to add this Program. Do tick on Domain Private and Public

on comparing, we need another Program to allow Vmware PCoIP Server

So click on Allow another Program. Click Browse..

go to path C:/Program Files/ Common Files/ VMware/Teradici PCoIP Server and select file pcoip_server_win32.exe and click Open

Once file is selected Click on Add

make tick mark on Domain, Private and Public to allow this program.

Now we need to allow some Port for view connection.
Open Windows Firewall and open Advanced settings

In inbound click on new Rule and select Port in it and click Next

In View Desktop we can see Vmware Blast(HTTPS) port 22443 is allowed in TCP

In View Desktop we can see VMware Horizon view Framework port 32111 is allowed in TCP

So we will give port 32111 and 22443. if in safer side you can give view basic required port 80,443, 4172

select Allow the connection and click Next

tick all option to allow it inter connection. you can select as per your connection and click Next

Give name to this port and Click Finish

In VDI we required port 80,443, 4172 TCP and UDP. so you can create one more rule for Port 80,443,4172 in UDP.
Since we have Create inbound Rule but we need to create Outbound Rule also
Select Outbound Rules and click on New Rule..
Select Port and Click Next
