I do not have experience of working in PDMS + Microsoft Azure environment. However, following is the meaning of Dabacon 580 if you are not aware of: 580 'File refresh failed'
which could well mean that there's a trouble / lapse in user's network.
Thanks Shrivallabha. Are there any tests to check the lapse in the network between the GPU (in which PDMS is installed) and the cloud drives in which the PDMS projects are stored?
