Cannot load webui - HTTP ERROR 400

[ts678]

@spupuz

I just use ipadress:port

Then this might be a different problem than the suggested solution in this topic had in mind:

@kenkendk

cannot access the web ui on 2 server

Duplicati will only accept localhost as the hostname by default. If you are using another hostname, you need to enable it with — webservice-allowedhostnames=hostname. Use the hostname * to disable the security mechanism.

It is not a new thing though, it should have been like this for several years?

and I’m also wondering if the option name change was intentional. From the server help text:

2.0.9.101

--webservice-allowed-hostnames: The hostnames that are accepted, separated with semicolons. If any of the hostnames are "*", all hostnames are allowed and the hostname checking is disabled.

2.0.9.102

--webservice-allowedhostnames: The hostnames that are accepted, separated with semicolons. If any of the hostnames are "*", all hostnames are allowed and the hostname checking is disabled.

You might need to go back to 2.0.9.101, or wait for the right developer to figure this out further.
