ZIA URL Category Override Not Applying: Cloud vs Location Policy Order

Zscaler · Techclick CLI troubleshooting lab

You recategorized a blocked training site to Corporate Marketing. Users still get the block page.

This is a live-ticket style lesson from Techclick Infosec. You will isolate the fault with CLI first, then prove the fix with one clean packet or log.

What you will be able to do

• Name the first CLI command to run on Zscaler for this ticket

• Separate the layer that is actually broken from the layer people blame

• Apply one scoped fix instead of a global disable

• Prove the ticket closed with a session, log, or counter

Quick answer

URL category overrides are not instant and they lose to a more specific URL policy. Check policy order, location scope, and the user cloud cache.

Why this ticket shows up

ZIA evaluates URL policy top-down. A leftover block on the exact FQDN beats a category allow. Clients also cache categories for a short time.

Symptoms operators actually see

• Override shows in the catalog

• Block page still names the old category

• Works for you, not for the branch

• Change was made 10 minutes ago

CLI first — copy this block

Run these on the Zscaler device or console named in the ticket. Do not skip the first show command — it tells you which later command matters.

nslookup training.vendor.com
curl -I https://training.vendor.com
# compare what the client resolves versus the ZIA Web log URL
ipconfig /flushdns

How to read that output

The Web log tells you which URL policy and category actually fired. If it still shows the old category, the override has not propagated or a more specific rule still blocks.

Triage order

1. Open one blocked transaction and read policy + category.

2. Look for an exact-URL block above your allow.

3. Confirm the override is for the same cloud and scope.

4. Flush client DNS and retry after propagation.

5. Move the allow above the generic block if needed.

Classic traps

What you see	Real cause	Fix
Override again	Exact FQDN block still sits above	Reorder policy
Tell users to wait a day	There is a more specific deny	Fix order now
Disable URL filtering	One site is miscategorized	Use override + order

Proof the ticket is closed

• Web log shows the new category and allow

• User loads the site

• Generic block still protects the rest

Say this in an interview

I trust the transaction's policy name, not the catalog screen. Order beats override.
