Connection refused

[samsonpwnz]

Hello, I am running this on a LilyGo-T-Display-S3 and after a few minutes I get red text at bottom of screen saying "Connection refused"
Is this an issue with wi-fi connection, or maybe flightradar24 rate limiting?
If I knew how to code it would be awesome to pull data from somewhere like adsb.fi. But this code is way above my head.

Hi Samson,

I do not know if flightradar is rate limiting. Maybe someone else reading this has the same problem?
However, could indeed also be DNS or WiFi problems.

What you can do to get more information is to let the debugging log run together with the display to see if there are errors or things time out. This might give a hint...

adsb.fi looks nice and provides the same data! Will have to take a look it that data source can be used but is certainly interesting.

adsb.fi lacks some data that is present on FR24 like origin destination etc...

I've just installed the project and getting a few of these also, no wifi issues or DNS issues present. It's not all the time as it'll just happen sometimes.

Hi Chickey,

This is server related. They do keep track how often you make a connection and might do some rate limiting.
Error -1 means timeout... Could be anything!
