I deployed LangFlow using Deploy on Railway button from here. The link is

https://railway.app/template/JMXEWp?referralCode=MnPSdg

It deployed successfully (Isee green checkbox), but when I try to open it I see an error:

This site can’t be reached

The web page at https://langflowailangflowlatest-production-e717.up.railway.app/ might be temporarily down or it may have moved permanently to a new web address.

ERR_HTTP2_PROTOCOL_ERROR

I tried 3 times and saw the same result.
Any suggestions?
