QDS suddenly throwing access denied error for input file locations

TusharDev_Qlik — Mon, 26 Jan 2026 18:19:17 GMT

Error: Cannot open file: 'excel config file' (System error: Exists for \ failed: ExistsException \ failed: boost::filesystem::status: Access is denied: io error).

Issue resolved after server restart and tasks started running fine.

Any possible root cause for this?

Hello @TusharDev_Qlik ,

Thanks for posting.

As per the description of the error I would think about such files being in use by another process and hence such IO/access denied issue.

If you ever face this again I would have suggest to try to open such files and see if that would have been possible or not. At the same time I would also suggest to run the process monitor as detailed here -, File Access and Process Monitoring - How to find l... - Qlik Community - 1712539 to detect if the file is locked by another process and detect which process is that.

I do hope this suggestion might help you to debug this issue if ever happens again.

Cheers,

Albert
