Error codes

Some parts of Betula user interface expose error codes for easier reference. This is a newer addition, so most of error states have no error codes. Existing ones are listed here.

BET-113

This error is specific for federated instances only.

This error is shown when you're visiting a visiting a Betula page logged-in, and the host you're requesting does not match the host specified in the Settings.

Most likely, the reverse proxy you are using is not passing the Host header along by default. You have to make it do so, otherwise the federation will not fully work.

For Apache, add the following lines to your VirtualHost:

UseCanonicalName on
ProxyPreserveHost on

For Angie or nginx, add the following line to your location / (where you have the proxy_pass directive):

proxy_set_header Host $host;

In rarer cases, you might see this error when accessing the instance from a mirror.

If you want to hide this error notification for any reason, use this custom CSS:

.notif[notif-cat="Host mismatch"] { display: none; }

BET-114

This error is specific for federated instances only.

The site address specified in Settings does not start with https://. In Fediverse, only HTTPS servers work, so you have to change the address so it uses the correct the protocol, even if you provide HTTP as well.

You should also have HTTPS properly set up with a reverse proxy. See Setting up a domain and HTTPS.

If you want to hide this error notification for any reason, use this custom CSS:

.notif[notif-cat="Wrong protocol"] { display: none; }
