Chrome Dangerous Site warning

Hello all,

Occasionally, my mailinabox’s Roundcube Web interface is flagged by the Chrome browser as a Dangerous Site. This seems random - it goes away for days, then comes back. Usually closing the tab, waiting ~1 hour, and reopening it fixes the issue. My certs are all valid (as reported by Chrome itself!) and IP address and DNS are stable with no changes.

Anyone else experiencing this issue?

Have you checked your IP address against the block/black lists? If you’re running on a server farm somewhere, there’s a fair chance the farm is running malicious software and your subnet might be implicated.
