Browser extension not able to sync

[alexandrestein]

Hello,

Description of the issue

My browser extensions are not able to sync with Vaultwarden:

It stats that last sync is from this morning but that wrong.

Surprisingly the native app does without any issue.

installed configuration

The server run from docker and via a HTTP proxy for HTTPS.

root@75d77d7320d9:/# /vaultwarden -v
vaultwarden 1.28.1

My extensions are the latest version:

I don't know how to provide more details.
Could you please help?

Check the logs of Vaultwarden and provide the log lines during the attempt of the sync.
One other item you can try to do is fully remove the extension, close the browser, and start the browser again and install the extension again. I have seen some reports of people who had similar issues and that is what solved it for them.

Very strange, OPTIONS requests are not send by the extensions. I have tried both Firefox and Chromium.
I never ever see any OPTIONS request being send or received.

It could be something else which is in between your Browser and Vaultwarden instance like.

• Firewall
• Anti-Virus tools
• Internet Proxy (not reverse proxy)
• Other browser extensions
• Reverse proxy config (WAF, ModSecurity)

The warning/error you see in the logs is correct, because there is no endpoint which matches that, and that also isn't something which is supported. The Bitwarden server does not have any OPTIONS endpoint, only GET, POST, PUT, DELETE.

So, which ever is causing the OPTIONS request, is causing your issues.
I suggest to use a clean profile for your Browser, install the Bitwarden Extension, and try if that works, if that is the case, look for which ever extension is causing the issue for you.
And, if you find which one, please share it with the rest of us :).

OK that a good way of troubleshooting.
I don't have time to do it now (my apologies because you are so responsive) but I'll let you know for sure.

Thanks

The issue seems to be on the browser.
I'm using Brave and I try to limit the accessibility/power of the extensions only when and where I need them.
For this raison, I set "site access" option in the extension to "On click" instead of "On all websites".

I'll verify if that works the same with regular Bitwarden server and if that's the case I'll open a case with them.

Thank you @BlackDex for your help.

Kind regards,
Alex

Now that you mention this, i think i have seen this before somewhere else. I don't think this is something Bitwarden can fix.

See:

• https://vaultwarden.discourse.group/t/cannot-login-using-the-web-extension-on-brave/1866
• Changing Chrome extension "This Can Read and Change Site Data"-permission breaks the extension bitwarden/clients#1612

Thanks a lot.
I added my Vaultwarden hostname to the specific site list and it seems to have fixed the issue for now.

You were of great help @BlackDex, thanks again.
Cheers

Sometimes we need to completely logout, re input the server address and then login. I've had this happen a few times, usually after doing a Docker update or changing some security settings.
