Problems with sharing internet over Wi-Fi(shared).

I created a shared WiFi connection through the network manager and my other devices can connect to it, but don't have access to the internet.
My computer is connected to the internet through Ethernet.
I can't seem to find any solutions on google.
Any help in figuring out how to sort this out ix be greatly appreciated.

It usually just works. Try to set IPv4 as required and IPv6 as ignored and reconnect. Also make sure te two cards are on different networks.

My phone says: Connected, no internet.
Even after setting IPv4 as required and IPv6 as ignored.
Is there a setting I might have changed on accident?
Also my internet connection is on ethernet and I'm sharing through WiFi. is it possible for them to be on the same card?

Make sure you have chose "Shared with other devices" in the IPv4 tab.

Make sure the two cards are on different networks. For example, what are the 1st 3 digits of the IP in the two networks on the PC sharing the connection?

Check the forwarding status of the ethernet card:
sysctl net.ipv4.conf.<card-name>.forwarding
