Hi. I didn’t change anything on my Vaultwarden installation. I just bought a new MacBook Pro M1 and I’ve installed the latest Bitwarden client (2024.2.0 build 20587). When I try logging in, I get this error message: ![image](https://global.discourse-cdn.com/free1/uploads/vaultwarden/original/2X/c/cf420b9f9318aaefed167908ca32d38e9c7d2a1b.png) What’s the cause for this and how to fix this? My other clients are all working fine (2 Android phones, 1 MacBook Pro Intel-based and 1 Windows 11 PC). Thanks, F. ---

Based on previous issues related to the same error seen here `cannot read properties of null (reading 'iterations')` I would suggest to see what version of the Vaultwarden server you are running, and possibly iodate that if you are using an outdated version. ---

I’m running vaultwarden/latest (docker from github). So, what’s next to try? BTW: the browser plugin is working both in Firefox and in Brave. ---

> [@Flavio](#): > > So, what’s next to try? Next is to verify that you are indeed using [the latest version](https://github.com/dani-garcia/vaultwarden/releases/latest) which you can do by running something like (just replace `https://vault.example.com` with your actual base URL): ```bash curl -s https://vault.example.com/api/config | jq .server.version ``` If it does not return `"1.30.5"` you are not using the newest `vaultwarden/server:latest` image but an outdated version. This could be the case because you use an outdated version of `docker` or have not actually pulled the newest image or recreated the container after pulling the latest image. ---

I don’t have the jq Linux command on my MacOS Sonoma, anyway: I am running the vaultwarden/server:latest as I have this in my Docker config. Adding to this, the fact that 1 hour ago I pulled the most actual “latest” version and rebuilt the container. Here the last part of the curl output: “config”,“server”:{“name”:“Vaultwarden”,“url”:“[https://github.com/dani-garcia/vaultwarden",“version”:“1.30.5”},“version”:"2023.9.1](https://github.com/dani-garcia/vaultwarden%22,%22version%22:%221.30.5%22%7D,%22version%22:%222023.9.1)”} **%** ---

Check the F12 Developer console of the desktop client to see what might be the issue. ---

Thank you for the hint. This led me to see that I had a type (missing 1 character) in the URL ☹ Sorry for bothering and thanks for the help!
