Hi @LawrenceKwan, can you check the Redis is running or not? If it is not running please first run it and then run the three project again.

Redis is an open source external tool mainly used for caching purposes and the ABP framework uses it to improve performance (as a distributed cache) of the templates/applications.
You can either download it as zip file and run the
redis-server.exefile or run via docker container. (https://redis.io/download)It should be up and running to run your application.

You can not check the Redis working condition via Visual Studio. You can check the logs to see your Redis server is running or not.
If it is not running, you can see a log like in the above image.
StackExchange.Redis.RedisConnectionException: It was not possible to connect to the redis server(s). UnableToConnect on 127.0.0.1:6379 ...

After I have start abp commercial soulution, I get 3 tab open, only the swagger show properly, and other 2 are showing error. See this :
ABPApplication.HttpApi.Host = > swagger tab ABPApplication.IdentityServer = > 500 server error tab ABPApplication.Web => An unhandled exception
Anything I need to set up for IdentityServer? I have already input the connection string.

The HTTP 500 Error has been fix, is because of database connection string issue.
And I find the below logs:

Hi @LawrenceKwan, as I've mentioned above you need to install the Redis and run it to be able to run the application.

If you have a tiered solution you need to use the Redis to share data between layers. (https://github.com/abpframework/abp/issues/5023#issuecomment-687854205)
You can see the pre-requirements for the application template by reading this document .
