Many thanx @austinwendt for your quick response. After Local 6.4.0 crashed I tried with both 6.3.1 and 6.3.0 without success. Local refused to start again with any version after the first crash. I also tried to restore the whole Local folder in Application Support from a recent backup. But since nothing worked I re-installed 6.4.0 and configured all websites from scratch. So I happened to overwrite the router log. And the local lightning log is flooded with the same messages. But nothing from the actual application crash. I also checked the console log but no crash or spin reports for Local. Right now I’m running Local 6.4.0 and it seems to be working after the re-installation. Besides the SSL problem from 6.3.1 that still persist.
