[quote="mcpeterc"]Hi.

I have a Windows server 2016 that runs a IIS ftp site. My users connect via port 990 and all worked fine a couple of days ago. Now when they log on I get this error:
[quote]TLS connection stablished. Waiting for welcome message... Access denied[/quote]
I checked the following:
[list]
[*] All users have write/write access to their own home-folder. Both on OS level and within IIS
[*] Reset the password so I'm 100% positive that the PW is the right one.
[*] Turned off the local firewall
[/list]
I use User isolation. I tried to give 'All Users' Read,Write access – that did not help
Can anyone help?

This is the log

This does not look like a WinSCP question.
Please consider asking elsewhere. For example at https://superuser.com/ or https://serverfault.com/

Problem seems to found:

There was double rules on 'FTP Authorization Rules' on both level FTP (shown here) and the same rules was on the localuser folder with holds each users isolated folder (shown here)

Apparently that's a no-go. Does anyone have any experience with this behavior?

Best regards

All of a sudden non of my users can connect - error: wrong password

Hi.

I have a Windows server 2016 that runs a IIS ftp site. My users connect via port 990 and all worked fine a couple of days ago. Now when they log on I get this error:

TLS connection stablished. Waiting for welcome message... Access denied

I checked the following:

All users have write/write access to their own home-folder. Both on OS level and within IIS
Reset the password so I'm 100% positive that the PW is the right one.
Turned off the local firewall

I use User isolation. I tried to give 'All Users' Read,Write access – that did not help
Can anyone help?
