Localtunnel alternative not working

Question

I connect my app to Localtunnel. It was working very well until last week, but now it's not working:

Answer 1

lt -h http://serverless.social -p 3000 

This was a quick fix that I found, and it works well

lt -h http://serverless.social -p 3000 --subdomain charls 

Will also let you have a custom subdomain name.
