Keep local folder up to date script, certificate problem.

Hi.
Im a new winscp user. I'm trying to get the included script "keep local folder up to date" to work for me, I've got an issue with certificate. It starts up and displays connecting (which is what the scripts says it shall do). After a couple of seconds (approx 15) it stops and says
Error calling.... system error. code 5. access is denied.
When checking the log it displays my organisations certificate and it displays that it needs confirmation to accept or decline the certificate.
I've searched the forum and found that the command -certificate=* shall solve the problem but I don't know where I shall put it.

I do not understand what can "system error. code 5. access is denied" have to do with a certificate. Please post logs.

Re: Keep local folder up to date script, certificate problem.

So you are using WinSCP .NET assembly, right?
I do not see any "system error. code 5. access is denied" in the log.
Anyway, if you want to trust this certificate, set SessionOptions.TlsHostCertificateFingerprint.

Or if you want an equivalent of the insecure -certificate=*, use SessionOptions.GiveUpSecurityAndAcceptAnyTlsHostCertificate.

I've now tried adding the session options. it gives me back the same error.
The not its printing "false" before connecting... i guess I'm doing something wrong here..
Please see attached files.

Keep local folder up to date script, certificate problem.

Hi Martin.
I manage to get it working. Thanks for the reply.
However I tried the function "delete files" which I assume would delete the files on the remote location after a successful transfer, nothing happened tho, I don't get any information in the PowerShell window and the files are still there. Have I done something wrong or is there more settings that I need to do in order to make it delete the files on the remote location?

Re: Keep local folder up to date script, certificate problem.

So show us what exactly did you do when you "tried the function "delete files"". And post a session log file.

Re: Keep local folder up to date script, certificate problem.

The Delete files option does NOT delete the source files. That would defy the very purpose of the "Keep local directory up to date" function.
See https://winscp.net/eng/docs/library_example_keep_local_directory_up_to_date#options
It seems that you are on a wrong track.
You might want to check:
How do I create script that synchronizes files and deletes synchronized files from source afterward?
