I am not a networking expert and have been using Sophos XG Home (v17) as my internet/WAN router for the past 3 months. I have not knowingly changed the configuration; however, from 2-3 weeks ago I can no longer directly access certain sites that require login credentials. The browser just times out and says the sites is not available. If I use a VPN tunnel (Express VPN) on my MacBook, then I can access these sites. Examples include 1password.com and sync.com. These sites do not appear to be blocked by any web policies.
What steps should I take to troubleshoot and resolve this issue?
