Opentopomap tiles not loading
« on: December 22, 2016, 01:08:17 PM »
Hi,

New tiles from tile.opentopomap.org will not load. I suspect this is because Topofusion does an HTTP GET and the server is redirecting to HTTPS. Wireshark TCP stream trace follows.

Thanks for the note on this.  And for the detail with the moved and TCP trace.  That helps a lot.

It must have been somewhat recent as at the last release of TF it was working.

We'll get it updated in the next version.  Sadly I'm out of country (in NZ) and away from my dev computer a few more weeks, so it'll be mid-Jan.

Cheers!

Thanks Scott.

I think its only been broken for a few weeks - though I'm a frequent user at first I put it down to a slow Internet connection.

Chris
PS Enjoy NZ - its on my bucket list!

NZ was such a place to visit!  Make it happen.

Got a new beta version out with OpenTopoMap back.  They moved to requiring https (SSL) for their tiles.  Not sure why that change makes sense for tiles, but a USGS site also made that change, so the timing was good to dig into adding it to TF.

I see that OpenTopo works in the US now, as well (and NZ).  That's good news.

Thanks for the post on this -- much appreciated.
