A priori it could be a problem with the proxy or the internet server that doesn't work. When restarting the workstation, do you still have the problem? I'm not sure if the space change bug is related.
@Bart, difficult to test, the machine is 500km from here and the operator is not comfortable (to put it mildly) with this kind of manipulation. I'll try to keep it as a last resort. I supervise and do the manipulations via Teamviewer.
@.PL, the machine was turned off last night and started this morning, and even restarted because of the errors. The nfocenter can be a track. For JIT: The application does not support just-in-time (JIT) debugging.
