Esri.OceanBasemap not displaying

[hansenjohnson]

I noticed that the map from Esri.OceanBasemap is not displaying (see provider demo page here). Perhaps it's due to Esri moving from an old to a new OceanBasemap? I was able to get around this issue by manually specifying the path to the new version of the basemap and reference layer.

From my side tiles are loaded on the demo page right now. Do you confirm ?

It is not working for me either and a downstream CI is also failing, with error 500.

Did you test with one IP or multiple ? Maybe your IP si blocked due to traffic limit from esri ?

This is from my local laptop, same with and without VPN. The same response from another machine elsewhere (via ssh). The CI that is failing in xyzservices is running on GHA, so completely detached from that. May it be that it is cached on your side?

'k got the 404 after testing from three different IPs.

This patch should do the trick :

PR is on the way.
