certificate exception - ZipException: error reading zip file 2

[anonymous]

What steps will reproduce the problem?

I tried to open JOSM, it didn't respond, I clicked again and ended up with 3 JOSM windows. Deleted two of them and then clicked 'Edit with JOSM' on HOT website - nothing happens (data doesn't load) but I get erros msg instead. Just retried the edit button and keep getting msg telling me that JOSM remote control did not respond and asking whether I'm connected etc.

What is the expected result?

What happens instead?

Please provide any additional information below. Attach a screenshot if possible.
