Validation of ssl-fingerprint faild after update

[ts678]

Welcome to the forum @mammut

@mammut

I tried to set “accept-any-ssl-certificate”

SSL and SSH are different. I assume this is SSH, which uses a fingerprint you accepted once.

@mammut

how to fix it

Maybe like this from a similar report.

Solution: Open Duplicati, edit the configurations of your backup, then go to Destination and hit Test connection, you will get a modal that offers to change the host key, hit OK and save the settings. Manually trigger a backup job and everything should work again.
