Issues with NightScout application

Hello,

We observe the issues with NightScout (nightscout · GitHub) application deployed in fly.io.
A few users reported the same issue yesterday at around 15:15 UTC on our local group.
All worked perfectly fine since a couple of month until yesterday.

Now we get the following response from the server:
Secure Connection Failed
An error occurred during a connection to XXX.fly.dev. PR_CONNECT_RESET_ERROR
Error code: PR_CONNECT_RESET_ERROR
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.

The VM reports “started” but 0 out of 1 checks passed. The log shows:

Reinstalling or restarting the NightScout application doesn’t help.

I’ve received an email about successful migration of the application to V2 platform at May 26th and until yesterday I didn’t observe any issues.
The IPv4/IPv6 addresses are assigned to the VM.
The NightScout application is deployed with a free plan. It is the JavaScript application. It uses the external MongoDB service (mongodb.com).

Please help with diagnostics/suggestions/solution/workaround.

Thank you

Hey,
Coming to Error PR_CONNECT_RESET_ERROR is given by Firefox when it cannot connect to the server.

The log says that proxy cannot react your instance which can be a problem with the instance itself.
or the app is good but it is taking time to respond which makes fly proxy think app is not working.

can you share application logs if there are any?
