This suggests the Server is one version ahead of the client. I would suggest fully uninstalling the client, then reinstall the new version.
I have seen this myself where the original version is installed in a different file path.

Not exactly, server and client versions are the same on the server.

The error message comes from the webconsole. I think the webconsole (war package) somehow could not be upgraded to the latest version.

After upgrade from 3.8.x to 3.9.156 web console can not login and shows an error message about incompatible protocol versions. (attachment included.)

Downloaded new version web console from https://netxms.org/download/releases/3.9/nxmc-3.9.156.war  but after installing cannot login and  version shows below right corner, still 3.8.405.

Upgraded Web interface (war) to the latest version 3.8.314 (https://netxms.org/download/releases/3.8/nxmc-3.8.314.war), but version text says 3.8.226 from about link.

Hi,

you should add to config file of your agent the following line:

Code Select Expand


EnableWebServiceProxy = yes

This change was done for improving security. Before 3.8 read access to agent allows you to do port scan (by requesting URLs with different service types and port numbers) and even local file access (using file:// URLs).

Best regards,
Victor

Thanks for reply, I have added above config to the agent file, but realized still not recieving polling data. 

But after adding this config to master server's agent file, polling is started. 

Is that result normal ?

- Web service proxy function in core agent now disabled by default
- Only HTTP and HTTPS are allowed in web service URLs

Please could you explain, how can I enable web service check from agent ?

After upgrade from 3.7 to 3.8, my web service dci polling has been stopped. I wonder if it is config changed issue ?

I also tested with below command, but console prints, 500: Internal error.

nxwsget 127.0.0.1 http://api.open-notify.org/astros.json number

What shoud I check ?

Is there any tutorial or documents, about how to setup dci for remote ssh server with authentication?

Great updates thanks.
