Unable to connetct to server running on localhost

giasone70

I successfully installed both host and server on the same machine.
The server works regularly, connects to printer, and is accessible by the webserver.
Similarly the host works nicely, slicing properly.
But they cannot talk one another. When I try the procedure for installing the printer on the host by Repetier-server, after I put in the API code, as I try to connect, I get a "socket error". It says that there is an exception in OnOpen.
I tried everyting, unsuccessifully.
Can you help me?

Can you tell the complete exception message?
Are you using 2.0.1 or an older version. Had some corrections for connection problems in 2.0.1.

I am using repetier host 2.0.1 and repetier server 0.80.3.
The complete error message is: "Socket Error: An exception has occurred during the OnOpen event."

I can add these other infos:

Here a thread, see last entry where someone had the same problem that System.Runtime could not be loaded:

I tried the solution, and it worked.
Probably the problem has to be reported to mono project's developers...
Thank you very much indeed for the help.

I'm having the same issue. Same error code, Ubuntu 18.04, Repetier-Host V2.1.3.

Looks like I just needed to install the libmono-system-runtime-serialization4.0-cil package.
