not-resolved URL for s3.us-central-1.wasabisys.com

Could you help me see why the s3.us-central-1.wasabisys.com comes back as a not-resolved category and is a threat?

That appears to be categorized as "Online Storage and Backup" in the URL filtering. You can test for your self here:

As for why your particular firewall is having a problem resolving that, it could be a number of things. See the following to debug:

The default Objects->Security Profiles->URL Filtering profile treat not-resolved as "Allow". So I would guess you are using a custom URL Filtering profile which has that category set to "Block". As a bypass, you could also create a custom URL Category with that URL and add it as Allow in your custom URL Filtering profile.

Thank you. I did. I think it is an issue with the firewall communication or a bug in our currently running firewall version (9.1.9).

I added it to the exclude allow-list until we upgrade our firewall and see that resolved this issue.

 

Thank you,

We have been running 9.1.14-h4 for some time and haven't had any issues with it. We did have problems when upgrading the URL filtering from PAN-DB to Advanced URL though as we have "not-resolved" and "unknown" blocked by default and that prevented the database from getting updates initially. Once we bypassed those categories temporarily the url-cloud could connect and download the initial database, at which point the categories could be blocked again and updates happened normally. 

Hi, We have the same situation. We have advanced URL filtering and now switching over from a standard local database to online when the license is expired from the standard and gets switched to the advanced one. Could you describe how to fix this issue? Disabled that two categories? Thanks in advance get more detailed descriptions.
