OK it starts but still you can not use resources, there is an error regarding Maxar imagery which can not be used.

Let's Encrypt changed certificate chain. Aaargh.

I think they are problem with Certificate of https://josm.openstreetmap.de, i have same problem at start of josm :

[stoecker]

Hmm, somehow the chain is broken. But why...

[Hb---]

Firefox shows that JOSM uses a new certificate valid from today on.

[stoecker]

Aaargh, Missing a ">" in the cert-renew hook which had no effect until the chain changed.

Fixed now.
