Is a website only loading partially? You can use the domain log to troubleshoot it.
First, turn on domain logging permission on your device by:
The domain log shows you in real-time host names that are being accessed on your network and whether or not they are allowed or not. For a site that isn’t displaying quite right, you can see the various domains that are being blocked. The “Rule Applied” column shows why domains are treated the way they are.
If a domain is being blocked by a blacklist, remove it from that blacklist.
If a domain is being blocked by a whitelist, there should be an airplane icon next to the rule. Click on it to send an unblock request. From your dashboard you can then approve the unblock requests.
