If you got the automatic updates on the bitwarden clients, they will show an empty vault if you are selfhosting vaultwarden.
It seems to be an accidental bug in the bitwarden clients that are assuming that they’re talking with official servers
It’s fixed with the latest release of the vaultwarden server that was published a few minutes ago



I found this comment on what happened by dani-garcia, one of the main devs:

There’s a reason you don’t do things like that…
Apparently nobody in that software team has heard about Knight Capital. They reused a flag and that coupled with a deployment failure that only lasted ~45 minutes caused an over 400 million dollar loss nearly bankrupting the entire company. Ultimately they ended up combining with another company.

I hadn’t heard of this one before, thanks for posting.
