Bug#779974: josm: invalid certificate

[Sebastiaan Couwenberg]

Thanks for the tile server info.

> c.tile.openstreetmap.org is an alias for tile.geo.openstreetmap.org.
> tile.geo.openstreetmap.org is an alias for se.tile.openstreetmap.org.
> se.tile.openstreetmap.org is an alias for oslo.tile.openstreetmap.org.
> oslo.tile.openstreetmap.org has address 31.169.50.10

The SSL certificate configured on oslo.tile.openstreetmap.org (ridgeback)
is in order like the other mirrors.

Does you browser generate any warnings when you access the tile directly?

I'm starting to suspect there is proxy on your local network or a
transparent proxy on the network of your ISP that intercepts the tile
requests.

Another option is horribly outdated cacerts for Java, this should be a
symlink to /etc/ssl/certs/java/cacerts which gets updated by
update-ca-certificates if you have not disabled this in
/etc/default/cacerts.

Which JRE do you use with josm (it logs this on the console if you start
josm from a terminal)?

Kind Regards,

Bas
