Read this doc ## "Network Error" in red text If you see `"Network Error"` in red text, that can be due to a VPN on your computer not being activated as expected. Some work VPNs will block Zenlytic if your work VPN is not activated. To fix this error, activate your VPN like you do to connect to other resources at your company. ## Username/password sign-in is missing If your workspace previously accepted username/password sign-in and that option is no longer available, your workspace may have been configured for SSO-only login. See [Enforce SSO-Only Login](/authentication-and-security/enforce-sso-only.md). Sign in via your configured SSO provider instead, or contact your workspace administrator. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.zenlytic.com/authentication-and-security/login_troubleshooting.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
