Thank you for reaching us out.
I would like to kindly ask you to generate the application log
while you are performing the same actions as reported. Please clear the log prior that to ensure only relative to the current issue records will be stored within the file. Once collected please send it zipped via this thread.
I would like to kindly ask you to try to connect to the TFS server but first remove 'tfs' from the Virtual Directory
field. Would that change the behavior?
Thank you in advance for your cooperation!
