This is happening when the corporate firewall replaces certificates of websites. And for some reasons Windows certificate store fails to validate the winscp.net replacement certificate – at least when queries the store the way WinSCP does.

Hello.

Is the issue with updating the application behind corporate firewall fixed?
I have copied the certificate posted in GitHub and save it in a crt file, tried installing this onto the workstation but it still doesn’t work, same error Check for Updates fails with error 80092013"

I have added this issue to the tracker:
Issue 2212 – Updates check fail because winscp.net certificate cannot be validated
You can vote for it there.

Hello Martin,

Have sent you an email the log file that you requested.
Seems like there is a TLS failure.

Tried to copy the certificate into a crt file and then import it into the Trusted Root Certification Authorities but the problem still persists.

Best regards,
Stelios

Hello.
Is there any update on why Windows 10 workstation on a corporate network with proxy enabled can not get WinSCP to update to the latest version?

Best regards,
Stelios

No same issue was with previous version as well…

@steliosh: Do you mean the problem is new in 6.1? If you downgrade, does it go away?

Hello.

I have upgraded to the latest version 6.1 build 13674 on Windows 10 22H2 on a corporate network with proxy enabled.

When triggering the option to check for updates I get the following dialogue box

Error checking for application updates

Certificate not trusted
Error:80092012 Chain index: 0, Element Index: 0
Server certificate verification failed: issuer not trusted

We disabled SSL inspection for the WinSCP.net site on our firewall, and the check update function completes successfully.

@martin: Created an account, got your email, sending you some details shortly.

Are you all getting the exactly same error message? Including the Error: 80092013?

Do you have some 3rd party firewall or other security solution?

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.

Recently install same versión on two differents Windows 7 computers, on 64 bits doesn't works but on 32 bits works fine.

@shaun.merrill: I have the same issue.
