Take a look at the attached screenshot. Even though the error message is somehow valid, the point is that I already see it in the repository manager that the connection cannot be made. Thus it should suffice to have the information only in the repository manager and not via a popup. Because of this, I need to remove now the server and can only add it, if the network connection allows so (we use tunneling software into the companies network and it's not always active).
Furthermore, please rephrase "The unexpected error..." to "An unexpected error...".
"... is currenlty unavailable." to "... is currently unavailable."
Something in addition:
I tried to delete now the CMR, but the UI blocks completely for a long time for the CMR auto update. Somehow it feels like some of the processing is not done in a separate thread but in the UI one. This should be taken care of.
