Preview App Page Errors - Cannot preview

I cannot preview the text app codes.

This is the page error I see:

Secure Connection Failed

An error occurred during a connection to SSL received a record that exceeded the maximum permissible length.


The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Please contact the website owners to inform them of this problem.

Hi @jjune

Can you please let me know the browser you are trying? as we tested it on couple of browsers and it seems to be working fine.

Would be helpful if we can get more details, that will help us to debug.

Sometimes it can happens due to firewall in the network, so you can try switching network as well.

Please let me know once you have these details.


Thank you for responding.

Still not working on Safari, Fox, Chrome
Looks like on all browsers I have been using, they all have failed.

I am on wifi connection, not sure how to address a firewall issue?

Also If I publish the App can I go back and sit it still and re-publish?


Hi @jjune

Not sure what the issue is because i am able to open it on Safari as well.

Can you try this URL instead: ?

Yes, you can publish the app and continue to do your changes and continue that way. It won’t impact anything.

Can anyone out there open this url without issues?


I also cannot see any published app code either?

I keep getting blocked, I may have to move to a different 3rd Party App building platform.

I am not sure why this is happening for you. Looks weird :frowning:

Are you able to access any of our other projects: ?

Hi @jjune Can you please check if you are able to access the URLs now?

We recently move our DNS provider to Cloudflare and now it should work fine.
