Can you ensure that your ISP or firewall isn’t blocking the replit.dev or repl.co domains?

I encountered the same issue when setting up my Firebase account today. After following the steps and clicking the run (>) button, I saw a fireworks animation, followed by a run command in the console tab, but nothing else happened. The webview did not load.

Update Firebase with Dev URL

Even after configuring the networking from port 8080:80, the webview still didn’t load. However, I did notice that the Dev URL is displayed in the Networking tab.

Here’s how I resolved the issue:

1. I deleted the Node.js Replit I had initially created and instead created a new Replit using the HTML, CSS, JS (Auto Refresh) template.
2. I hit “Run.”
3. It worked!

Please Note:
Prior to resolving the issue, I had updated my Firebase secret keys, but I’m not certain if this played a role in fixing the problem. My conclusion is that the issue might have been related to not properly configuring the port for the Node.js file to run on the webview.

I hope this helps!

After doing some research, it appears that this high latency and errors happen intermittently every couple of months. Are you still having connection issues?
