Recently installed Vaultwarden (v1.26.0) on Suite 9’s Embassy OS and so far things seem to be working fine, except that I have a warning error message on the main page, under [HEALTH CHECKS].

^^^^^^^^^^^^  
WEB UI  
Error while fetching URL: [http://vaultwarden.embassy:80/alive](http://vaultwarden.embassy:80/alive)  
^^^^^^^^^^^^

What is this error message and how can I get rid of it, or correct it?

Thank you in advance.

I have no clue how the environment you use is working. But that health check is normally used by docker to verify if the server is still running.

How this works in your environment i don’t know. So I’m unable to help in a good way. Only thing i can imagine is that the domain used there is not accessible by whatever is running that check.
