Select a location in USA Massachusetts 2. Select MassGIS 2023 or 2025 Orthos 3. Note tiles will not display - HTTP error 200 at any zoom level 4. Create new updated wmts feed from current MassGIS documentation (ex: https://tiles.arcgis.com/tiles/hGdibHYSPO59RG1h/arcgis/rest/services/Massachusetts_Aerial_Imagery_2025/MapServer/WMTS/1.0.0/WMTSCapabilities.xml?cacheKey=9955572174118a43) 5. Note same error ==== What is the expected result? Proper imagery tile display ==== What happens instead? HTTP error 200 in the main screen ""Image not returned for tile"" error in the debug information (below) ==== Please provide any additional information below. Attach a screenshot if possible. MassGIS Ortho links are provided automatically in the Imagery menus via the Wiki but same occurs if you get the latest link from MassGIS support pages and create a new feed. Current links are correct and valid. Work perfectly in QGIS. {{{ Revision:19555 Build-Date:2026-03-30 09:42:59 Identification: JOSM/1.5 (19555 en) Windows 11 64-Bit OS Build number: Windows 10 Pro 25H2 (26200) Memory Usage: 800 MB / 24192 MB (215 MB allocated, but free) Java version: 21.0.10+7-LTS, Azul Systems, Inc., OpenJDK 64-Bit Server VM Look and Feel: com.sun.java.swing.plaf.windows.WindowsLookAndFeel Screen: \Display0 2880x1800x32bpp@60Hz (scaling 1.50×1.50) \Display1 1920x1080x32bpp@60Hz (scaling 1.00×1.00) Maximum Screen Size: 2880×1800 Best cursor sizes: 16×16→32×32, 32×32→32×32 System property file.encoding: UTF-8 System property sun.jnu.encoding: Cp1252 Locale info: en_US Numbers with default locale: 1234567890 -> 1234567890 VM arguments: [-Djpackage.app-version=1.5.19555, -XX:MaxRAMPercentage=75.0, --add-modules=java.scripting,java.sql,javafx.controls,javafx.media,javafx.swing,javafx.web, --add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED, --add-opens=java.base/java.lang=ALL-UNNAMED, --add-opens=java.base/java.nio=ALL-UNNAMED, --add-opens=java.base/jdk.internal.loader=ALL-UNNAMED, --add-opens=java.base/jdk.internal.ref=ALL-UNNAMED, --add-opens=java.desktop/javax.imageio.spi=ALL-UNNAMED, --add-opens=java.desktop/javax.swing.text.html=ALL-UNNAMED, --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED, -Djpackage.app-path=%UserProfile%\AppData\Local\JOSM\JOSM.exe] Dataset consistency test: No problems found Plugins: + DirectDownload (36474) + DirectUpload (36474) + ImportImagePlugin (36474) + PicLayer (273) + Review.Changes (1.1.1) + apache-commons (36474) + ejml (36474) + geotools (36474) + jackson (36474) + jaxb (36474) + jts (36474) + opendata (36474) + reverter (36474) + undelete (36474) + utilsplugin2 (36497) Tagging presets: + %UserProfile%\AppData\Local\JOSM\muskratty_presets.xml Map paint styles: + https://josm.openstreetmap.de/josmfile?page=Styles/Modified&zip=1 + https://pasharm.github.io/New_basic_style_for_JOSM/New_basic_style.mapcss Last errors/warnings: -
