Trouble with EPSG:3006 WMTS service

[nkamapper]

I am having trouble accessing the following WMTS service:
​https://api.lantmateriet.se/open/topowebb-ccby/v1/wmts/token/9b342b7d9f12d4ddb92277be9869d860/?request=getcapabilities&service=wmts

After I enter it as a new WMTS layer in the imagery window, JOSM delivers the following error message:
javax.net.ssl.SSLHanshakeException: Remote host closed connection during handshake.

On a different MacBook, where the imagery had already been entered under an earlier JOSM version, no tiles are displayed (never worked).
The imagery works in QGIS, but with a "problem" message

The imagery is listed as EPSG:3.6:3006. There have been reported difficulties in interpreting this service elsewhere but solutions have been found, examples:
​https://github.com/BruTile/BruTile/issues/44
​https://gis.stackexchange.com/questions/120325/what-is-proper-succession-of-coordinates-while-specifying-topleftcorner-in-tilem

The imagery in question is the only open and official topographic map for Sweden, recently under CC0 license and the best available background map for the country, so it would be great if it would somehow work in JOSM.

Here is the technical information provided (in Swedish, sorry):

Please provide any additional information below. Attach a screenshot if possible.

Possibly related to #11701

[Don-vip]

Linked to r8584. Not all swedish projections have been defined.

In 13684/josm:

fix #16224 - update definition of SWEREF99 projections for Sweden

[Don-vip]

The map is nice :)

[nkamapper]

Thank you for the rapid response. Will include the map in Maps/Sweden when the fix is live in the stable version.

[nkamapper]

Would it be possible to define the relevant map layer in Maps to get direct access to that WMTS layer without choosing it every time in the menu?
Like WMS without wms_endpoint.

@wiktorn: is this what you're working on?

You can already add it, no need to wait. The stable is expected very soon anyway.

Correct, that's what I'm working on. I hope to get this finished in May.

In 13733/josm:

Imagery definition refactor

Extend imagery definitions by:

• allowing setting default layers for WMS_ENDPOINT and WMTS
• allowing setting minimum expires time for tile for this imagery
• allowing setting custom headers that will be sent for all requests

(get map, get capabilities) for this imagery

Additional changes in code:

• use TileJobOptions to pass miscellaneous options to loaders
• refactor WMSImagery to use SAX parser

See: #15981, #7953, #16224, #15940, #16249

[wiktorn]

In 13734/josm:

GUI for imagery definitions refactor

Extend preferences panel by:

• allowing setting default layers for WMS / WMTS
• allowing setting minimum expires (expert mode)
• allowing setting custom headers (expert mode)

See: #15981, #7953, #16224, #15940, #16249
