hi guys, I have implement group chat in my internal infrastructure. I have implement and compliance in different server but the same database.

while I send file in the group chat, I get error message

A file transfer error occurred. The underlying connection was closed: An unexpected error occurred on a send.

first time I think it’s problem Web Service has stopped like picture below

but here don’t worry, the problem is not web service. I was solved this problem with any edited configure IIS in the server Group chat. please check point this below to solve the problem :

1. Open IIS manager, right click in the MGCWEBService and click Manage Application > Advance Settings.

2. Click Physical Path Credential > change authentication user with member RTCComponentUniversalService

3. And I also change Physical Path Credential in default website on compliance server (the way same I did on the group chat server)

4. after that I restart IIS with command iisreset

after I did the way I still get the error but this time different error like below

a file transfer error occurred. server was unable to process request —> access to the path ‘\servername\Web Service\UploadTemp’ is denied

here I just give only permission in the folder sharing Web Service, I give both permission the first in the security permission and the second sharing permission

  • Everyone
  • Administrator
  • RTCComponentUniversalService

here I give Permission Full Control

after that I try again to send file in the group chat and the result is working
