Oxygen 23 was just released--maybe you could try installing it and see if the issue has been resolved? Using Ultratools.com I get this entry for 209.250.6.266: Source: whois.arin.net IP Address: 209.250.6.226 Name: ARMOURCLOUD-HOSTING Handle: NET-209-250-6-0-1 Registration Date: 12/9/19 Range: 209.250.6.0-209.250.6.255 Customer: Armour Cloud, LLC Customer Handle: C07470992 Address: 7558 W Thunderbird Rd Ste 1-434 City: Peoria State/Province: AZ Postal Code: 85381 Country: United States Cheers, E. -- Eliot Kimber http://contrext.com On 11/20/20, 12:58 PM, "oXygen-user on behalf of Patrick Durusau" <oxygen-user-bounces@oxygenxml.com on behalf of patrick@durusau.net> wrote: Greetings! I'm trying out Oxygen XML Editor 22.1 on Debian and I'm getting this persistent message: ***** The Wellformed XML Scanner validator tried to connect to: 209.250.6.226:80 The host 209.250.6.226:80 is not in the list of trusted hosts.

The host in question, 209.250.6.226, just displays a Testing 123 page to show an Apache HTTP server is working. I keep denying it access but there's no persistent block that I can find. Thoughts? Suggestions? Thanks! Patrick PS: I've run whois and written to the technical contact but the popup makes it sound like I'm originating the request.
