I am unable to connect through IP.
May be its open for SK, but i also tried other ports like 8888, same problem with other ports too.
No i'm unable to access the localhost:8080 on the host. It also gave me the same error page on browser.
Here below in quotes is the error while opening the URL in browser:

when i simply enter the URL: http://SK or http://localhost then a white page open.
Altair EmployeeHi @Gru Have you started the server on the host? To do it you need to run the standalone.bat
It should be on
[Your Installation Path]\bin\standalone.bat
check after running it try to access through localhost:8080 on your host computer.
If that doesn´t work please upload you log
You'll find it on
[Your Installation Path]_HOME\log

Yes, i started but not working.
But when i open/ execute standalone.bat, the cmd prompt screen did't hold, it automatically close before 1 sec.

Here is the log, from C:\Users\SK\rapidminer-server\rapidminer-server-home\log
And here is standalone.log from path C:\Users\SK\rapidminer-server\rapidminer-server-9.2.1\bin
when i am entering my URL : http://SK:8080
No admin page is open, as i told earlier the page that open having error message:

I don't know if your are installing on a Windows Server but check if you have created the JAVA_HOME variable.
Try to create that JAVA HOME variable looking at this link:
https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/
Also check the java version compatibility:
https://docs.rapidminer.com/
@rfuentealba which version of java is not compatible with Server? on the log I read he is using jdk-12.0.1

@MarcoBarradas from Java 9 onwards, Oracle removed some functionality, hence it's not backwards compatible. A safer bet would be to use Oracle JDK 8. I'm not entirely sure if it works with OpenJDK 8 too, worth the test.
But, for starters, you can install Oracle JDK 8, not declare the %JAVA_HOME% variable and set it up on standalone.bat.
Let me read the logs first and I'll be back in 10 minutes.

It took me less than 10 minutes.
@Gru you can install JDK 8 from Oracle and modify the following files in your RapidMiner Server installation.
That way you don't have to uninstall RapidMiner Server and install it again.
BTW, use your Java location. Mine is on a Mac.
Hope this helps,
Rodrigo.

File: rapidminer-server-home/configuration/version.properties
rm.server.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home
File: rapidminer-server-9.2.1/bin/standalone.conf
JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home"
File: rapidminer-server-9.2.1/bin/standalone.conf.bat
set "JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home"<br>

Altair Employeehi - your log files show that RM Server is finding Java 12 instead of Java 8. THIS WILL NOT WORK.
You MUST use Java 8 for RM Server. Please see RM Server Installation docs for more on this. It is very likely that if you have both Java 8 AND Java 12 installed, RM Server is looking in the wrong place (see discussion above about JAVA_HOME). Hence I would uninstall all other versions of Java except Java 8, then re-do installation process.

Currently I am using JDK 8. But stucked in the same problem
I have installed Java SE Development Kit 8u211. There is another one thats 8u212.
Is the problem occurred because of i installed 8u211 instead of 8u212.

Another error picture
New Log file....
and standlone.bat file is not opening
SEVERE: Error trying to connect to the database! java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES) at
No there is no problem with Mysql database, the connection is successfully established.
I know you see the log file, but there is no problem with db, i thinks that error in log is because, when i filled the entry while installing db, i fill wrong password after that i correct it and connection established.

When i click start button, the rapid miner server service not running. It shows me above message. Why ?

Altair Employee@Gru @rfuentealba I have had no problems with MySQL and, being a SQL amateur, I find it a bit easier to use than PostgreSQL.
It's clear from the log that your pwd correction did not take for some reason. TBH, if it were me, I would delete the installation and start from scratch. You probably have something messed up in the config and it will take less time (and you will be better off) with a new clean install. And don't mess up the pwd

Now look the problems that occurred after clean and full installation.
Problem 1: Rapid Miner service cannot start properly. Here below is the picture showing a pop-up error message.
How to resolve this ? See the picture . . . There is a problem 1.

Problem 2: The standalone.bat file is unable to execute or run. When i click it to open, it not hold or visible and immediately automatically closed. A empty command prompt screen is open for few nano seconds and then disappears. I never see anything in cmd prompt.

And the MAIN PROBLEM, that occurred is i am unable to open admin page of server or rapid miner server is not open.
Here is my server URL. (which didn't work)
http://SK:8080
and error screen that occurs is attached with this post below.
I am very very very thankful to ___________ ???
If someone solved my problem. So that i haply continue my work on Data Mining and analytics.
I am doing my Phd work by taking Rapid miner as a tool. I delay my Phd because of my failure to connect with server. Its my last chance on Monday.
I thankful to all who helping me, but still cannot connect to Rapid miner server.
Waiting for problem solver . . . . . . . . .

SK has the port 8080 open?
Can you access the localhost:8080 on the host?
