Oracle Reports 12c REP-51002: Bind to Reports Server repserver1 failed on Windows 10

Alexander ReichmanSep 28 2022 — edited Sep 30 2022

Hello everybody
I have installed Oracle Forms and Reports 12.2.1.3.0 on Windows 10 using the document which I have already used before for installation http://shipingzhong.cn/sites/default/files/oracle_forms_12c_installation_for_windows.pdf
I have created standalone reports server
createReportsServerInstance(instanceName='repserver1',machine='AdminServerMachine')
and ReportsToolsInstance
createReportsToolsInstance(instanceName='reptools1',machine='AdminServerMachine')
After starting Standalone Reports server and trying to connect with
http://laptop-cmtt9so4:9002/reports/rwservlet/showenv?server=repserver1
I am getting the error
REP-51002: Bind to Reports Server repserver1 failed
I saw many posts and Oracle Notes and tried what was recommended in the following discussions
REP-51002 while running the reports in 12c (12.2.1.2.0) windows — oracle-tech
REP-51002: Bind to Reports Server rep failed — oracle-tech
Tried to change multicast to naming services as it was recommended here
https://community.oracle.com/tech/developers/discussion/4125494/rep-51002-while-running-the-reports-in-12c-12-2-1-2-0-windows
Edited $DOMAIN_HOME/config/fmwconfig/components/ReportsServerComponent/<standalone repserver>/rwnetwork.conf
Commented multicast and enabled namingservices
Started the naming services:
$DOMAIN_HOME\reports\bin\namingservice.bat 14021
Wheh I am running rwdiag -findAll
Naming service used to locate servers
-------------------------------------
Naming Server host = laptop-cmtt9so4
Naming Server port = 14021
(1) repserver1 : Type = server : Host = NA
Looks the host name which I put in host file was not recognized
<ip address> <my laptop host name>
In rwEng-0_diagnostic log I always see this error:
[2022-09-26T09:59:18.899-04:00] [reports] [INCIDENT_ERROR] [REP-50125] [oracle.reports.engine] [tid: 1] [ecid: 4f801726-b52e-4087-8b88-fd9d3650bcd7-00000002,0] [EngineName: rwEng-0] REP-50125 : org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No [[
...
Caused by: java.net.ConnectException: Connection refused: connect
I believe the problem can be in my Windows configuration.
When I am running netstat -aon I don't see my laptop name laptop-cmtt9so4
