Thank you for your answer, I'm now logging in fast as ever the patch has worked.
I'm still having problem with APMCloudMonitorAgent though.
I've already worked on similar problems as mentioned in Document ID : KB000044276 and Document ID : KB000105783 but now I don't know why the integration 9.5.3 isn't working.
Have a nice day
Ps Later on i discovered it was a proxy problem not in our configuration. Thanks again for your reply.
