Gateway Connection Error

Ignition
1

Hello everyone,

I encountered the following error while configuring a gateway connection. Both virtual machines are running on the same physical host, so theoretically, traffic between them shouldn't pass through a firewall. This is the first time I've run into this issue—what should I do next?

Connection attempt to 'ws://10.145.1.103:8060/system/ws-control-servlet?name=ignition-5eebd5a8229f-master&uuid=2b058902-0e5f-40e1-9f4d-d811b7301602&serializer=protobuf&url=http://10.145.1.104:8088/system' failed! 
Response code='400', error message='org.eclipse.jetty.websocket.api.exceptions.UpgradeException: org.eclipse.jetty.websocket.core.exception.UpgradeException: 400 Illegal character CNTL=0x15'.

400 Illegal character CNTL=0x15
The ASCII character 0x15 is for NAK.

10.145.1.103 and 10.145.1.104 are trying to set up a connection. 103 rejects the connection from 104, probably because there’s something wrong with the connection information.

Please check whether the connection information is written correctly and doesn’t contain any whitespaces. It could be in any field, so be thorough.

I checked and didn't find any spaces.

It doesn’t necessarily have to be spaces, it could be a typo as well in any of these values:

  • receiving IP address / port
  • Transmitting IP address / port
  • UUID
  • Gateway name
  • IP address settings on the machines themselves

Port 8060 can only be used for gateway network SSL connections. You have to check the “Use SSL” checkbox in your connection settings.
