Thank you for response. Turned out that the errors were not related. After clearing caches as mentioned in the help article I was not able to view pages with correct admin url. in various browsers or on different machines. A friend in another location verified problem where all attempts to enter storefront were redirected to frontend site. My host however said there were no problems. Turned out it was an likely an ISP issue. We installled VPN and voila the problem is solved. Perhaps ISP was attempting to block or just making adjustments. This happened once in past and only resolved spontaneously after 3 days or so..
