Part-DB Browser Plugin (Firefox) error...

[GitGatGone]

So I have Part-DB (v2.16.1) set up on a Raspberry Pi using OpenMediaVault and Docker, and I'm able to log in at 192.168.x.yy:8080. I'm trying to get the Browser Plugin to work, but all I get is "Could not reach Part-DB: NetworkError when attempting to fetch resource." I'm using http://192.168.x.yy:8080 as the Part-DB base URL, I'm logged in as an admin before I try the plugin, and the Browser plugin and Generic Web URL Provider are both enabled in the server settings. Any insight into what I'm doing wrong?

Have you authorized the plugin to access that domain? You will get a popup by firefox when setting the url.
You have to press yes there, otherwise the browser wont allow you the access.

And i think firefox is quite strict, if you have clicked no once, it wont ask you again, ever...

I have the same issue with Firefox 153.6.0esr, all permissions are granted. User Logged In. Same case using http:// and plain IP and port to access Part-DB.
Maybe this extension only support standard ports 80 and 443 and we have to run Part-DB over proxy ?
For example adding https://demo.part-db.de extension is able to establish connection, so it would indicate problem with accessing over URL with port or maybe something in Apache in Container.

works after reverse proxy and .local domains

It turns out chrome worked, but i didn't get a popup from firefox, and I'm not sure what i need to do to force firefox to be happy. I've had this happen at work, too, with other apps where chrome is fine but firefox is more strict and I've never figured out where to look to make it happy.

Can also reproduce the same error.

do you access it by http:IP:PORT or kind of proxy with .local domain because I don't know if I should spent time configuring proxy ?

So it turns out this is some known bug/quirk in firefox, that it does not allow for port patterns in URLs

I will change how it builds these patterns, and it should be fixed with the upcoming browser plugin v1.2.1
