Resolution

Step 1: check the configuration in transaction code SM59.

On the "Technical Settings" tab, the radio button "Start on Application Server" must be selected and "mdxsvr" must be entered as the program.

On the "Unicode" tab:
- For kernel version below 7.49: the radio button "Non-Unicode" must be set .
- For kernel version of 7.49 or above: "Unicode" must be set.

Step 2: Download the latest RFC library file

For kernel version below 7.49: You must make sure that the required files (executable mdxsvr, RFC library in a 32-bit version, non-Unicode, librfc32.dll for Windows platforms or librfccm.so for Unix/Linux, the mdxpars.dll library for Windows platforms) exist on every application server.

For kernel version of 7.49 or above: You must ensure that the required files (executable mdxsvr, platform-specific NW RFC library file such as libsapnwrfc.so for UNIX) exist on each application server.

Download the RFC library file - How to download RFC library file.
For kernel version below 7.49: The RFC library file is in non-Unicode, please do not download the file under "<SAP kernel version> UNICODE".
Find the directory of the mdxsvr - Directory of mdxsrv.exe.
Copy and replace the RFC library file in the directory.

Step 3: Check connection in SM59. If error does not happen any more, the connection issue is resolved.
