Work with local OSM tile server and https

[Wo1fgarr]

Good day!
I encountered a configuration issue while working with MapFish. I set up a local OSM server, which is accessible via both HTTP and HTTPS.
If port 80 is open on the server, MapFish prints the map with tiles without any issues. However, if I close port 80 on the OSM server and specify port 443 in the config.yaml file for MapFish (for the OSM server address), the map does not print with the tiles.
In the browser and via a direct request (e.g., https://some_addr/osm/0/0/0.png), I can retrieve the tile without any problems.
I couldn’t find any documentation in MapFish regarding HTTPS configuration. I’d appreciate your help if I missed a section in the documentation or any hints on whether it’s possible to use HTTPS with MapFish at all.

Upd1: i'm working with mapfish in geoserver.

Best regards.

Do you use a valid certificate? Mapfish print works only with valid certificates!
Do you take a look at the logs?
