Yes, I've still had the issue recur after clearing the host cache, unfortunately. I switched my router to use the Google DNS servers for my network rather than the ones from my ISP, which I'm hoping further mitigates it.Have you seen it recur after clearing the host cache?
Clearing the browser cache typically only clears cached images, scripts, cookies, local settings, and other content. DNS cache, which stores the mapping between a domain name (e.g. disboards.com) and its IP address (108.61.75.210), is typically a different cache that has to be cleared separately.How is this different than going into settings and clearing cache?
You should only need to clear your DNS cache, not the browser cache, to resolve this issue (at least temporarily). Since clearing your DNS cache using my suggestion above does not clear cookies, it will not impact your active logins.
