I have a Function App in azure and when I hit the URL of the function app it says "Function host is not running." I am not sure where I have to check and what needs to be changed. I tried restart but still no luck.

This usually means that there is some bad configuration in your function app which is causing the host to fail to start up. Things like having an invalid host.json or an invalid proxies.json file are a possible cause.
To diagnose, it's best to look at the function host logs. If you open your function app in the Azure portal and turn on log streaming, you should be able to get more information about what's going on.
If you're not able to find anything, please let us know the name of your function app either publicly or privately and we can help take a look at the logs for you.

I was getting this after adding dependency injection support - I had an error in the startup class which stopped the host from starting.

Thanks for responding. I see that time trigger function in it is getting an error thats causing host to stop.I resolved the error now Function host is working fine.

In Azure Function v2 you are required to set the runtime version in host.json
