DataSource.Error when i try to update my report on server

[Kirilliy]

I have report with 7 xlsx files, they are located on network folder.

When i try update my report on server i have these error: 

DataSource.Error: No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept.

How i can fix this error?How i can see how many connections accepted for my network folder? 

When i update report localy - all ok.

Are you using  file connectors, or a folder connector?

file connectors

Please try with a folder connector instead.  It may or may not help with the issue but will make maintenance easier.
