Overpass APIs - read timeout #5

Closed padmalcom closed 11 months ago

padmalcom commented 11 months ago

Hi @westnordost, first of all thanks for your fantastic library.

I implemented a simple demo but I couldn't get a connection to the overpass API server (https://overpass-api.de/api/). I tried several servers, listed here: https://wiki.openstreetmap.org/wiki/Overpass_API

But I couldn't get a connection to any of them, I get a "SocketTimeoutException: read timeout".

Hm well, this doesn't seem to be related to the library. A socket timeout means that a timeout has occurred on a socket read or accept and could have various reasons, none concern this library. I do not operate any of these servers and don't know how they behave nor do I manage your network setup. If you are sure this is nothing about your network, I suggest you read the FAQ or alike on the individual servers, maybe you are required to supply certain information in the request or something.

Thanks for the fast reply, I forgot to metion that https://overpass-api.de/api/ returns a 403 forbidden. My thoughts were that the URL syntax changed.

What worked for me was increasing the timeout when creating the OSMConnection:

return new OsmConnection(
                "https://overpass-api.de/api/",
                "AmazingUserAgentButBetterUseYourOwn",
                null,
                240_000);

The 45 seconds default timeout raised a SocketTimeout with a query that had no elements as result. 🤷

PS: Thanks Tobias for the great work 🎉
