still the same problem here though.

Additionally, when launching JOSM it says

"JOSM tried to access the following resources: 
https://api.openstreetmap.org/api/capabilities
but failed to do so, because of the following network errors: 
java.security.InvalidAlgorithmParameterException: Prime size must be multiple of 64, and can only range from 512 to 1024 (inclusive)
It may be due to a missing proxy configuration. Would you like to change your proxy settings now?"
