What's Wrong?

Bug: Claude in Chrome — all sites blocked in Cowork mode (was working previously)
Plan: Pro (individual)
What happened: Claude in Chrome was able to access Etsy.com and Printful.com in my Cowork session last night (March 29, 2026). Today (March 30), every single site returns "This site is blocked by your organization's policy" — including google.com, amazon.com, etsy.com, and printful.com. No network requests are even attempted; the extension blocks navigation before any request is made.
Impact: My entire Cowork project depends on Claude managing my Etsy shop (PersonaPatterns). Without browser access to Etsy and Printful dashboards, I cannot use Claude to check orders, respond to customers, manage listings, or monitor fulfillment. This is the core use case I'm paying for.
I am not on a Team or Enterprise plan — there is no organization admin setting blocklists. This is a personal account.
Steps to reproduce:

Open Cowork session
Claude in Chrome tries to navigate to any URL
Returns "This site is blocked by your organization's policy"

Expected: Same browser access I had last night.
Related issue: #30861

What Should Happen?

I need it to work on etsy.com like it did yesterday.!!!

Also happening to me, all websites get this error

Same problem. I just installed it to try it out and ended up with this issue.

I have the answer, my issue was in Chrome using the extension.

So this setting must be set to whitelist sites, or make all sites available. Take your pick.

[dquillman]

my issues was with some specific sites. I already added the sites but they were not working..... BUT it is fixed NOW!!! :)

Same issue. Pro plan (individual), no organization. All sites blocked with "blocked by your organization's policy". Location: Asia. Clearing cache/cookies did not help.

[philip-newzoo]

Happening to me with my company websites, but it looks like it works fine on Google.com and it's blocking legitimate QA test automation.

[dquillman]

Yes...but there was a bug that was recently fixed. Before this setting was ignored. Dave Quillman 512-680-4852 ***@***.***

This was my issue. Somehow, this setting must have changed itself during an upgrade or magically started working. The setting itself is found in the web app settings interface.

I'm on Pro plan extension version 1.0.66.

The work around that I used to allowlist sites one-by-one instead of just turning everything on:

claude.ai (I use the windows app) → Settings → Claude in Chrome → Allowed websites → Add website → restart Chrome completely

This is a terribly clunky way to allowlist a site. The claude subpanel in Chrome should have a single button that allows me to allowlist a site on-the-fly. Shutting down and restarting Chrome for every allowlist is excessive.

-edit for more info-

I re-installed Claude because somehow cowork was disabled and the app asked to re-install to get it operational. Upon re-install, the allowlist of my websites was lost in the Chrome extension. I had to, once again, restart Chrome -- but didn't have to change any setting anywhere else.

So

allowlisted site was working in Claude for Chrome extension -> re-installed Claude windows app -> site now blocklisted in Claude for Chrome extension -> restarted Chrome -> site again allowlisted.

-edit 2 for more info-

Everything was working, and then my allowlisted site was blocklisted again. Some kind of allowlist sync issue, I guess.
