FlightRadar24: "Problem fetching data from the server. Please refresh the page to continue"

[melvenx]

Thank you so much for developing this! I am running it on a Mini PC connected to a Sony Bravia TV and everything seems to be working great except FlightRadar24. It displays the map from OpenMaps but not any airplane traffic.

Instead, it displays a message "Problem fetching data from the server. Please refresh the page to continue".

I live near an airport and would love to have my TV displaying the air traffic overhead while HA is happily automating everything.

I verified that HAOS is able to access the Internet and is not being blocked by a firewall. The FlightRadar24 app and dashboard is also working through Home Assistant with all of the other devices I use to access HA.

I suspect it might be related to issue #118 and could be resolved with a different browser engine like Chrome? I am happy to troubleshoot and provide logs, whatever would help.

Thanks!

Please do include logs and troubleshoting

Here is my Home Assistant Core log. Please let me know if you are looking for a different one. There is a recurring error related to FlightRadar but it does not seem to have anything to do with this issue. I tested FlightRadar on HAOS-Kiosk at 6:19am today (8/9) and no corresponding errors appeared in the log.

Unfortunately, the FlightRadar24 integration does not seem to have any other logs that I have been able to find. The map shows live flights and flight data on any client-device with a "full browser". It does not work at all from AndroidTV due to browser limitations (the map does not even display), but it does work fine from my Android mobile which has better browser "plumbing".

Since both HAOS-Kiosk and FlightRadar24 are working perfectly otherwise, I am not sure how to troubleshoot this. If you have any ideas, I am happy to test them. Oh, I think I forgot to mention that I am running HAOS on an AMD Ryzen mini-PC (x86) if that matters.

Here are my core log and a couple of screenshots of how FlightRadar24 looks via HAOS-Kiosk and one from a PC showing a working map with a live flying helicopter.

THANK YOU for your help.
