WebApp can not fetch external URLs anymore

Question

Last night at around 11pm all of a sudden my NodeJS app in a WebApp container all of a sudden could not fetch external URLs anymore. This has been working for months so far.

The errors I get vary between these messages:
* socket hang up
* Client network socket disconnected before secure TLS connection was established
* Internal Server Error
* Client network socket disconnected before secure TLS connection was established

I get the same errors when I use curl from inside the container but I am unable to reproduce it from my local MacBook or some other systems I have access to.

Since I get the same errors with curl on the containers cli I doubt that the error happens in my application and has to be somewhere in the network stack of my WebApp setup.

Any idea where this issue might come from?

I just tried to dig a little deeper into that issue but it all returned to normal at 6:18am UTC this morning. I still have no clue what it was - I did not change any configuration or didn't deploy the app.

I have no clue where this issue came from.
