SharePoint - Failed to delete document library file

Question

Problem

Encountered error "Cannot complete this action. Please try again" when trying to delete a file from document library.

Troubleshoot

• Tried user Administrator/Farm account with highest privileges to delete file, but still encountered the same error.
• Checked the "Minimal Download Strategy" is not enabled.
• No useful information from ULS logs and no correlation ID is provided on the error page.

Hi @Ching Song Lim ,

I tried bypassing the load balancer by logging into individual WFEs and verified that the above errors were not happening in both scenarios.

Temporary Fix: Disable the “Minimal Download Strategy” feature from site settings >> Manage site features page.

Permanent fix:
Compared response headers from SharePoint WFEs and Load balancers using fiddler – Found load balancer response missing the response header “Accept-Encoding” field!
