Symptom

You have checked your network settings and you did not find any problems yet.

But in the import overview,  when you open the import queue for one system, and when you refresh the import queue, you got error below:

RFC communications error with system/destination %%

ashost=<hostname>,sysnr=,lang=E,client=<nnn>....

Error while determining the RFC connection parameters

For example, you might get the error screen below:
