[GraphHopper] SRTM Service Connection Refused

[Peter]

Hi,

you can change the elevation provider to use CGIAR or a different host
for the SRTM data. See here the code and how to configure this (should
be documented in config-example.properties too)
https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/GraphHopper.java#L497

You cannot configure currently the timeout, but you can increase it via
configuring the downloader (setTimeout) in the ElevationProvider. Please
create an issue/pull request to make this configurable.

For the other thing you have to create an issue too I think.

Regards,
Peter
