Permission Denied

jeffpahf

All,

A, lot of variables, the client switched from a primary server to a QA server which may not have had the latest host server certificate; that is likely resolved, but the odd thing is that the folder in question that has worked many years w/out issue, stopped allowing file uploads on/after 5/22, and today I set to FULL rights, but is responding with Permission Denied; and the only reason I/we think the certificate is resolved is the exit code went from 9 to 11

Any hints or suspects (besides the many shown here)

Details: What we think happened is that this client setup in Serv-U in year 2017, either created or reverted to an older process that predates 2024-03-31 update when a new Cert was created. This is assumed because the other many times a daily file uploads to other folders is working and this on was working w/out issue until 5/22; AND nothing on the host side is known to have changed, especially to a subfolder. And, the client is uploading many other files to other folders that Inherit full rights from their home directory 

Since 5/22 they were not able to upload files, receiving the message; Permission Denied; adding more logging in Serv-U we see after Permission Denied a message implying that they had not accepted/stored the certificate

Today, I granted specific Full Permissions to the /Invoices folder, and I think that the Client finally updated the server certificate, so the message changed 
To try to be clear the bold line below matches the prior

Hi @jeffpahf

This one is likely because they are pointing to a different server and the host key is different, so their script or software probably has the old key cached.

I think this could be related to local filesystem permissions on the serv-u server, not Serv-U settings. Give that a check over. Serv-U might not have permission to that folder with the account it is running under.

Let us know how you get on.
