To use Mark AI from your company network, ask your IT team to add the following domains to your network’s allowlist:
app.markcopy.ai
api.markcopy.ai
ws.markcopy.ai
files.markcopy.ai
documents.markcopy.ai
sso.markcopy.ai
unleash-proxy.markcopy.ai
api.liveblocks.io
To keep it simple, you can allow *.markcopy.ai instead of the subdomains above. Some features use other domains, listed in Domains in detail below.
📧 Also allow the email sender no-reply@markcopy.ai, so that sign-in codes and password reset emails arrive.
⚠️ Make sure WebSockets (wss://) and long responses go through without buffering, and that no filtering category such as Generative AI blocks Mark AI. Each point is detailed below.
Proxy settings
No buffering on api.markcopy.ai: AI answers are streamed (text/event-stream)
Timeouts of at least 30 seconds idle and 5 minutes per response
WebSockets (wss://) allowed to ws.markcopy.ai and api.liveblocks.io
SSL inspection and browser isolation: exempt *.markcopy.ai and api.liveblocks.io if problems appear
Standard HTTP methods allowed (GET, POST, PUT, PATCH, DELETE)
Recognize a network block
What you see | Likely cause |
A page with your company’s branding says Access denied, Website blocked or This category is not allowed | The web filter classifies Mark AI as an AI tool |
The sign-in page or the app keeps loading | A required domain is blocked |
The AI starts writing, then stops or never finishes its answer | The proxy holds back long responses |
Your colleagues’ cursors and comments don’t appear, or Reconnecting… stays on screen | WebSocket connections are blocked |
File uploads fail or images don’t display | Access to file storage is blocked |
Everything works from home or on 4G, but not at the office or on the VPN | The company network filters part of the traffic |
💡 For a quick fix, send your IT team a screenshot, the time it happened and the link to this article.

Web filtering categories
Many companies block AI tools by category, so Mark AI can be blocked even when none of its domains is.
Filtering tool | Categories that may block Mark AI |
Zscaler | Generative AI, AI & ML Applications, Newly Registered Domains |
Netskope | Generative AI, Uncategorized |
Palo Alto Networks | artificial-intelligence, newly-registered-domain |
Fortinet (FortiGuard) | Artificial Intelligence Technology, Newly Observed Domain |
Cisco Umbrella | Generative AI, Newly Seen Domains |
⚠️ A domain allow list takes priority over categories: it is the most reliable fix. Also check data protection (DLP) rules for AI tools, which can block file uploads.
