This site can’t provide a secure connection

stylishprice-eu.backendless.app sent an invalid response.

ERR_SSL_PROTOCOL_ERROR

application ID = A20959C8-58A0-45C4-BEEE-FF108415524A.

I’ve not worked this app in several months but have kept it on a paid subscription.

I was unable to reproduce this error with the domain itself. I tried opening https://stylishprice-eu.backendless.app in both Google Chrome and Firefox, and the page loaded without any issues. Could you please check again if the problem is still present and, if so, provide more details on how to reproduce it?

Regards, Andriy

I’m having the same issue. Haven’t worked on my site in several months and now I can’t access it:

The site opened just fine for me. Try connecting it using a mobile Internet connection instead of wifi to make sure it is not your router:

Hi, Chrome just would not work. I jumped to Safari and it did work. I tried cleaning house in Chrome but I still can’t get Chrome to run.

This is the certificate information as reported by a browser - I do not see any issues there.

I also ran a certificate check here:

and it found no issues:

I believe the problem is related to your local network or the provider. I am sorry, but I am not sure what we can do here.
