It really depends on whether the channel/broadcast you are trying to watch has a stand-alone streaming app for its content. Not all broadcast channels have that. Some broadcasters have free streaming apps that have limited content, some have free apps for all their content, some have a paid standalone subscription, and some can only be viewed on a streaming device if you have a paid subscription to a package, such as with a cable subscription or a streaming package that includes their content.
A streaming device like a Roku or others is in a lot of ways like a cable box. Yes, there are some free channels you can stream over the network, similar to what you could view directly through the internet or even over the air with an antenna, but like a cable box, you usually have to pay to get specific content.
For example, I can get my local channels via their free apps on Roku because they have made apps for that purpose, but those channels have limited content, usually just their newscasts.
To be able to view their full broadcast, I have to either try to view via an antenna or in my case, I pay for a subscription package through Spectrum cable where I can stream the channels through their app. I no longer have cable boxes, which saves me some money per month, but to be able to view all the content I previously had, I kept a subscription to the channel package I had with cable boxes.

You could also try factory resetting your device and see if that helps as well. It is possible that it is your internet provider has given you an IP that is pinging to a different location. You can view that information if try one of the many Ip identifying programs online. If that is the case, you could also try resetting your modem/router and see if you can get a new IP or contact your IP provider and request a new IP address. A VPN could also be causing an issue too if you have one.
