Hi @micheljanos,

 

can you please have a look on the server.log? There should be more information. See: https://docs.rapidminer.com/latest/server/administration/error-logs.html

 

Best,

Martin

It's been my experience with this error that there is a connectivity problem.

Re: server error 500 occurred

Hi Zoltan,

 

Please check the steps I took today:

 

1. Started RM v. 7.6.001 and unsucesfully tried to connect to server. I was normally connecting, but have not used the Server for a few weeks.

2. I re-installed mySql and RM server (V.8) and was able to connect to App Designer front page but not to Web interface getting the 500 error.

3. I made and update to RM v.8, by Marketplace.

4. After re-starting RM the update is not installed and I can't even connect to Server.

See att. Server log

 

best,

 

Michel

Re: server error 500 occurred

@micheljanos it seems that one of the components of RM Server could not start due to an illegal host name:

 

Caused by: java.lang.IllegalStateException: java.net.URISyntaxException: Illegal character in hostname at index 10: tcp://NASA_SERVER:5672

Please open $RM_SERVER_INSTALLATION$/standalone/configuration/execution.properties and change the property `jobservice.queue.activemq.host` to an IP or a valid hostname according to https://www.ietf.org/rfc/rfc2396.txt

Afterwards please restart RapidMiner Server and check whether it is working now.

@micheljanos You can open the file execution.properties with your favorite text editor.

I would recommend to re-install RapidMiner Server and use your correct hostname or simply localhost to make it work properly.

Hope that helps, we will get your server up and running!
