Connection refused for certain websites - RBK853 V4.6.8.2
I cannot reach certain websites using my RBK853. It works fine if I connect the computer directly to the fiber media converter (or with mobile data), so the connection and websites are running fine, ...

Yes, laptops are able to resolve those two URLs into IP addresses.
This is me trying to telnet www.folksam.se:
$ telnet www.folksam.se 80
Trying 193.183.162.44...
telnet: Unable to connect to remote host: Connection timed out
Same goes for the other address bygghemma.se with "Connection timed out".
Now, circumventing the Orbi and trying to connect directly to the fiber media converter gives this successful result:
$ telnet www.folksam.se 80
Trying 193.183.162.44...
Connected to www.folksam.se.
That's why I think there must be something in the Orbi that blocks it đ

(except that this is consuming your life) What an interesting problem!
Those are both secure web sites (https), so I presume they accept connections on port 80 in order to redirect them to port 443.
Would you mind sharing the IP subnet that the fiber unit has assigned to the Orbi router, and the IP subnet that the Orbi has created for the LAN site?

I'm unsure what you mean by IP subnet but the fiber unit assigned 100.72.124.114 with subnet mask 255.255.255.0 to the Orbi router and LAN address is 192.168.1.1 with subnet mask 255.255.255.0

192.168.1.x is typical for a residential router LAN subnet. The 100.72.124.114 is definitely unusual. (i.e. it is not a typical 'private' IP
https://en.wikipedia.org/wiki/Private_network )
If the fiber unit will accept connection by a smartphone (i.e. WiFi), my assumption is that it is a combination media conversion/router/WiFi unit and that it would assign a private IP to the Orbi router.
On the router's web interface, the Advanced Tab home page, when you click the blue box Connection Status, what does it show for "Default Gateway"?

It should be a regular fiber media converter as there is no wifi, interface or other router functions. I connected my smartphone to the fiber unit with an ethernet dongle when testing (Samsung S22 Ultra supports ethernet). My smartphone and laptop both reports 100.72.122.79 when plugged into the fiber unit, so I guess that's the IP assigned to the ethernet dongle I used when plugging in those devices.
Default gateway is 100.72.124.1
