FileZilla doesn't remember/find root certificate

#1 Post by MartinZ » 2021-06-23 08:23

Hi alltogether,

when connecting with FileZilla to a server, I receive the popup "The certificate of the server is unknown. Please check...."
After confirming that the server certificat can be trusted always, the download works fine.
BUT:
The next time FileZilla is started, the popup appears again.
I've checked that the root certificate (Certum Domain Validation CA SHA2) is present on the computer under trusted root certificates.
The server we try to contact is xxx.kasseerver.com:21 with TLS1.3

Thanks in advance for any idea why Filezilla does not find the root certificate in the keyring.

Martin

I'm using the latest version of FileZilla (updated yesterday) on Windows 10 Pro in a windows domain.

I did some more research:

The file %appdata%\FileZilla\trustedcerts ist properly updated when accepting a certificate.
After rebooting the computer andd logging in as the same user the file exists. But ist changed to an old filezilla version 3.35.3 from 2018.
The installed version is 3.54.1.
It contains an older version of the server-certificat that is expiered.
The file sitemanager is from 2018, too. Despite of having replaced it with a new version.

So there is some mechanism that replaces the new correct files with old ones.

Does anybody has a hint which mechanism that could be or where the files, that are restored, are stored (and might be deleted)?

Thanks

Martin

Are you using a roaming Windows profile? If so, make sure it synchronizes back to the domain controller when you log out of Windows.

Thanks a lot! Your hint pointed me to the correct solution.
It was a group policy that replaced the the correct files!
Thanks!
